Git: Could not resolve host github.com error while cloning remote repository in git

What I did: I have created a remote repository on Github and I am trying to clone the remote repository on my local machine. While cloning I am providing the clone URL & target folder.

But every time I try to clone, I am getting this error:

Error: "fatal: unable to access 'https://github.com/hyperion057/spring-repo.git/': Could not resolve host: github.com"

What do I need to do to connect to GitHub ?

What command are you using? Are you cloning by https or ssh? I just tried to clone your project and it worked.
I am using git GUI and i'm cloning by HTTPS.
Open a terminal and execute git clone git@github.com:hyperion057/spring-repo.git
do i need to configure proxy settings? because my office has got proxy servers.
The errors you are getting are basically telling you it cannot connect. You have probably set your proxy to the browser, but not on the entire machine. Try to set the proxy accordingly and try again.

I got a similar error, and it's caused by incorrect proxy setting. This command saved me:

git config --global --unset http.proxy

https version:

git config --global --unset https.proxy

This is worth trying even if you never touched the proxy setting and aren't behind one currently. I think this was somehow set automatically during a past hotel stay (or when using in-flight wifi) where a proxy was in place.
Note that this will only unset the HTTP proxy. If you're having difficulty connecting to HTTPS locations, use the sister command 'git config --global --unset https.proxy'
This solved my problem. I was getting an error from homebrew "fatal: unable to access 'github.com/caskroom/homebrew-cask': Could not resolve proxy: wpad" and this resolved it.
I never touched the proxy settings, didn't change any of my previously working settings, and have never even used a proxy. But this is what worked to fix my problem. Thank you.
Thank you so much. Could you please tell me why this problem occurs?

do i need to configure proxy settings? because my office has got proxy servers.

Yes, you can do so by setting HTTP_PROXY, and HTTPS_PROXY environment variables.

See "Syncing with github":

set HTTPS_PROXY=http://<login_internet>:<password_internet>@aproxy:aport
set HTTP_PROXY=http://<login_internet>:<password_internet>@aproxy:aport
set NO_PROXY=localhost,my.company

(To avoid putting your credentials -- username/password -- in clear in the proxy URL, see below)

Note the NO_PROXY, to allow to access internal site to your company

You also can register that in your git config:

git config --global http.proxy http://<login_internet>:<password_internet>@aproxy:aport

But if you have incorrect proxy Git settings, remove them:

cd /path/to/repo
git config --unset http.proxy
git config --global --unset http.proxy
git config --system --unset http.proxy

git config --unset https.proxy
git config --global --unset https.proxy
git config --system --unset https.proxy

# double-check with:
git config -l --show-origin | grep -i proxy

No credentials needed: use genotrance/px.
If you are, as I am, in a company behind a NTLM proxy, all you need to do is:

unzip px-v0.4.0.zip anywhere you want

change the px.ini config file (put it in %USERPROFILE%), chaging the server line: [proxy] server = proxy.my.company:8080 <= use your company proxy:port listen = 127.0.0.1 port = 3128

use HTTP(S) proxy variable without your credentials! (the px proxy will reuse the ones from the current Widows session, either through Microsoft SSPI or Microsoft Kerberos)

That will give you:

set HTTPS_PROXY=http://127.0.0.1:3128
set HTTP_PROXY=http://127.0.0.1:3128
set NO_PROXY=localhost,my.company

This isn't always the issue. See my answer below, but sometimes if you mac is out of disk space you need to delete a few files and restart the terminal.
what are the and ?
@Sara The login/password of your Windows session when you are using an enterprise proxy.
it is unclear, please give an example regarding setting http_proxy.
@CătălinaSîrbu What part is unclear? My setting regarding http_proxy is done with the commands at the end of this answer.

Spent a couple hours trying to fix this.

Re-connecting my wifi did the trick.


lol, that was the problem at my end too. I had my browser open in another computer (it sucks the life out of my work Mac otherwise). And I was looking for the solution in another PC. Didn't notice that the work computer had got disconnected.
If you are conncted to VPN, one of the tricks is definately to re-connect again. Thanks a much, that saved my life.
I did not do anything apart from switching my wifi on and off multiple times (on my laptop). After around 40 seconds past the last on/off the issue resolved.
u saved me from re-starting my system and from changing 1000's of configurations
My default DNS provider sucks so I usually set up Google for DNS resolution. 8.8.8.8 and 8.8.4.4

another possibility, I ran into this problem myself. But it was after I had installed a VPN (which was unrelated and running)

turning off the VPN, fixed the issue.

for the record, I was running "Viscosity" VPN on my MacBookPro


heh, for me it's the other way around. github.com resolves only when I'm on VPN. :|
For the record this is also with ExpressVPN on a Macbook Pro
Its your internet issue

I've had the same issue after running out of disk space. Closing and reopening terminal fixed it one time. Restarting my Mac the next.

Some easy things to try before jumping to random commands:

restart terminal tab

restart terminal app

If disk is full (or close to it) free up some disk space then restart terminal app

restart machine/OS


I experienced this on a Mac. Restarting my terminal fixed it.
Same here on a debian install.
Restarting my mac worked, but it looks like just restarting my terminal might have been sufficient. I hope people see this, because I went on a mini wild goose chase for about 20 minutes trying the various commands on this and other help sites.
Just closing a terminal tab is sufficient as well.
I was facing this problem on WSL2/Ubuntu and only your solution - restarting OS (windows) - solved this problem. Thank you.

Ruli

Would like to note, when I did Brian's solution:

git config --global --unset http.proxy

Make sure to quit and restart terminal. Mine didn't resolve until I did that.


Note that reset didn't work for me here: I had to fully kill my terminal session.
Im using WSL with VS Code, I had to close everything down and reload it back up. Thanks

192.30.252.128 is the current IP of github.com which can be set in your local DNS (/etc/hosts in Linux and C:\Windows\System32\drivers\etc\hosts)


Current IP Addresses are listed here: api.github.com/meta (from help.github.com/articles/about-github-s-ip-addresses) and here is a tool to convert CIDR to ip range : ipaddressguide.com/cidr

From the answer here -> my solution is specific for Windows Subsystem for Linux (WSL) users. None of the answers relating to proxies are relevant to my solution.

If you are unable to run a ping command e.g.

# WSL
ping google.com

Then it is likely your file at /etc/resolve.conf is corrupt. To fix this run the following in a WSL window:

# WSL
sudo rm /etc/resolve.conf

Then open a Powershell terminal in Administrator mode and run

# Powershell
wsl --shutdown
Get-Service LxssManager | Restart-Service

This should fix the problem, which can be tested by running the ping command again.


worked for me after I booted first time into a clone of my windows 10 on a new SSD

I solved it by using this command

$git config --global http.proxy http://enter_your_proxy:enter_port

Maybe it is because of your internet access, You can try:

ping google.com

If you get this error again, there was problem in your network configuration.

In my case, on a Windows box, my TCP/IP stack seems to have needed to be reset. Resetting the TCP/IP stack of the client PC caused git to start behaving properly again. Run this command in Administrator mode at a command prompt and retry the git command:

netsh int ip reset

Manually disabling and re-enabling the network adapter via the Control Panel produces a similar result.

I suspect DNS resolution problems inside the TCP stack on my Windows box.

When you tried above solutions and nothing helps, you may need to checkout your local network settings and try to add 8.8.8.8 and your local router ip to the DNS filed.

I had this very similar error as following.

C:\wamp\www\myrepository [master]> git push
fatal: unable to access 'https://github.com/myaccount/myrepository.git/': Couldn't resolve host 'github.com'

Actually, the prompt message has told us where's wrong.

https://github.com/myaccount/myrepository.git/

When I check my github, I found my github repository's HTTPS url is

https://github.com/myaccount/myrepository.git

I don't know how this happened. The wrong url has been set up by installed Git Shell automatically.

Once I remove the '/' at the end, I can push successfully.


Hi John - Can you provide details as to how you removed the '/' ? I'm having the same issue you describe above.
How did you fix it? Encountering the same issue.
git remote -v to see the remotes. git remote set-url origin https://github.com/USERNAME/REPOSITORY.git to set the remote.
Even I have the same issue. I don't see "/" with git remote -v, but I see is while doing git push. How to solve this?
So how do you remove the extra "/"? I am getting this when I try to git clone

All, I want to let you all know that I was having this same issue. I solve it by resetting my remote URL git remote set-url origin https://new.url.here I found how to do this from this answer but I had to change hit to https: Change the URI (URL) for a remote Git repository

Just in case future generations stuck in this too: For me what worked (on mac OSX) was to set my DNS with opendns 208.67.222.222 , 208.67.220.220. I get this numbers here: https://www.opendns.com. For some reason, my dns configuration reseted to the default numbers (my local ip I guess), and I was not able to connect to neither github, brew or rubygems. Sorry for the misspelling.

Edge case here but I tried (almost) all of the above answers above on VirtualBox and nothing was doing it but then closing not only the VirtualBoxVM but good ole VirtualBox itself and restarting the program itself did the trick without 0 complaint.

Hope that can help ~0.1% of queriers : )


Figured a ctrl-F "virtual" would find this... Nice to see you friend :-) Just did the same fix -- needed to restart the VM and VB, then all was well. Imagine something got messed up while playing with buffer overflows in some server code on the VM :P

One reason for this issue could be wrong/empty /etc/resolv.conf file.

The way I resolved this issue in my centos 7 minimal is as follows: my /etc/resolv.conf was empty and I added the following lines:

nameserver 192.168.1.1
nameserver 0.0.0.0

where 192.168.1.1 is my gateway, in your case it can be different.

If you have a VPN needed to connect to your enterprise account and do a "git pull" this error will occur, just switch on your VPN and it will work.

After restart git bash below works fine for me:

As a suggestion for Ubuntu servers, you can write down essid and password of router in your /etc/network/interfaces file:

iface [en0 || your wireless driver no necessarily en0] inet static
    address 192.168.1.100 / (something for your static ip between 1-255)
    netmask 255.255.255.0
    gateway 192.168.1.1 / (this is the ip of your router)
    dns-nameservers 8.8.8.8 / (you can use whatever you want)
    wpa-ssid qwertyuio / (this is router id)
    wpa-psk qwertyuio / (this is router password for wireless connection)

When I got this error while pulling a repository to my server, I wrote wpa-ssid and wpa-psk and restarted. Then it worked.

EDIT: I faced the same issue again and this time it was because of the inconsistency in router signal levels. My connection was not strong, that was the problem. However, the solution above is a real solution for static ip

In my case I open a new terminal and problem solved. I don't know exactly what caused the problem in the first place though.

After clearing the Empty cache and hard reload from the Chrome dev tool of https://github.com/ thats works for me.

Open your Chrome dev tool and right click on reload icon, then you can see this option.

the simple solution to removing extra "/" from git clone remote is putting the url in parentheses. git clone " "

Different from all these solutions, in my case, I solved the issue when I restarted my terminal (or open another window).

I guess my case was very rare, but GitHub was out down. Check their webpage to see if it loads properly.

I faced a different version of this problem while cloning the git repository via https:

fatal: unable to access 'https://GIT_USER:GIT_PASSWORD@github.com/organization/repo.git/': Could not resolve host: GIT_USER

The problem was there were restricted characters in the password and it needs to be URL encoded. Additionally, if you are using 2FA (two factor authentication) then personal access token should be used in place of the password.

Searching the error condition above yields this page on google, so hopefully this answer will save someones time.

For Windows user using TortoiseGit, see Settings-Network, and enter proxy settings directly there. Easiest fix I've had to do all year.


u
user1994956

I ran command on terminal, then restarted terminal.

git config --global --unset https.proxy

But it din't work. Then I turned Off and On my wifi on Mac.

git push

It worked.

In case your proxy server doesn't have username and password -

Change it like this-

192.168.49.1:8282 - <your-proxy-ip>:<port>

git config ---global http.proxy 192.168.49.1:8282
git config ---global https.proxy 192.168.49.1:8282
