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

Question

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 ?

Answer 1

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

Answer 2

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

Answer 3

Spent a couple hours trying to fix this.

Re-connecting my wifi did the trick.

Answer 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

Answer 5

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

Answer 6

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.

Thanks so much, issue was killing me!

Answer 7

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)

Answer 8

i have same issue and solve it by using this command

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

Answer 9

It works for me

git config --global --unset http.proxy

OR

git config --global --unset https.proxy

Answer 10

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.

Answer 11

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.

Answer 12

You can try these two commands,it helped me.

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

Answer 13

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

Answer 14

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.

Answer 15

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.

Answer 16

This solve the issue

git config --global --unset http.proxy

or https

git config --global --unset https.proxy

Answer 17

Today I face with the same issue, this is also providing another possibility. I did all suggestions above but still seeing the issue. I have no way but restart my mac.... Problem solved....

Answer 18

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

Answer 19

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.

Answer 20

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.

Answer 21

Based on other solutions, what worked for me :

1. writing this in terminal :

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

2. restart - router restart - mac

You can first try -2- , If that not working, then try -1- and -2-

Answer 22

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.

Answer 23

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.

Answer 24

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 : )

Answer 25

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

Answer 26

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

Answer 27

Restarting terminal in Mac worked.

Answer 28

If all the above answers failed to solve your problem, try rebooting the router.

Worked for me.

Answer 29

Maybe it help someone somewhere, in my case (which was a private repo of git), host was suspended, so the issue was with my GitHub server and the administrator resolved it.

Answer 30

It worked for me when I used "service apache2 stop"
