Hey @shiv1490. This error message seems to indicate a connectivity problem. Do you currently have any antivirus software installed other than the default antivirus that ships with Windows?

Additionally, are you using a proxy server to access the internet? Git requires special configuration to work behind proxy servers, see #1998, #2789

[shiv1490]

Hi All,
Issue is resolved now. This was happening because I was behind a corporate proxy. I used below commnad to resolve the issue

git config --global http.proxy http://proxyuser:proxypwd@proxy.server.com:8080

Thanks

[Jaaess]

@shiv1490 👍
the command worked with me.
git config --global http.proxy http://proxyuser:proxypwd@proxy.server.com:8080

[imsrgadich]

Check this out as well. it helped me.

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

[DoganM95]

in my case it was a firewall rule (cmd not having internet permission), created by the company i work for

[kutajay]

Tried the following
git config --global http.proxy http://proxyuser:proxypwd@proxy.server.com:8080 and
git config --global --unset http.proxy
git config --global --unset https.proxy
but none seems to work for me; could it be a possible internet strength isssue?

[SethuSP]

Tried the following
git config --global http.proxy http://proxyuser:proxypwd@proxy.server.com:8080 and
git config --global --unset http.proxy
git config --global --unset https.proxy
but none seems to work for me; could it be a possible internet strength isssue?

I too tried the same. It does not work for me as well and i do not think it is related to internet strength. Not sure why.

[JCDigital27]

This method works for me!
reboot>
then establish connection to internet...
then>
#git config --global --unset http.proxy
#git config --global --unset https.proxy
then>
#git clone https://(.........................................).git

[davidbeery]

Why does this fix work?
What is it about the http/s.proxy global config that interferes with the internet connection?

[steveward]

@davidbeery The --unset flag can fix the issue where Git will attempt to establish a connection through an invalid proxy configuration (i.e. the user is actually not behind a proxy), which causes Git operations to error out. If you are using a proxy then you will want to keep that proxy configuration line in order to ensure Git operations work successfully.

[RoderickKennedy]

@JCDigital27 i have the same problem, whe i use the solution, but it not work?
when i use curl -I https://github.com, it show the error.
curl: (6) Could not resolve host: github.com; Unknown error

[manishak-kumari]

@shiv1490 👍
the command worked with me.
git config --global http.proxy http://proxyuser:proxypwd@proxy.servers
should i copy and paste the same line given by you above or i need to do some change?

[sadkisoft]

Please i need a help
My code is :

$url="https://api.sellercenter.net/?Action=GetProducts&UserID=***&Signature=***&Format=JSON";
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 5);
curl_setopt($ch, CURLOPT_TIMEOUT, 5);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_MAXREDIRS, 3);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Accept: application/json'));

	$parsee = curl_exec($ch);
	$result=json_decode($parsee,false); 
	$errno = curl_errno($ch);
	$errmsg = curl_error($ch);
	$httpcode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
	curl_close($ch);
	var_dump($errno, $errmsg, $httpcode, $parsee);

the result is 👍
int 6
string 'Could not resolve host: api.sellercenter.net; Host not found' (length=60)
int 0
boolean false

@sadkisoft this issue tracker is for GitHub Desktop -- if you have specific programming questions I'd recommend our Community Forum or StackOverflow.

[jlcalderon]

Hi everybody!

I had the same problem and I solved differently. First, I was getting the error, because I created the Local repo and initialized before I had an online instance of the repo. Then manually, online in my git hub account created the repo to push my local files on it. When I tried to push the local repo into the online I got the error.

Solution:

1. Remove the origin to clear out the initialization by:
   git remote rm origin

2. Then try again the command lines:
   git remote add "your link to the repo".git
   git push -u origin master

Hope this help somebody.

@shiv1490
the command worked with me.
git config --global http.proxy http://proxyuser:proxypwd@proxy.server.com:8080

Did it work for Ubuntu

[steveward]

@Harshada-github the proxy configuration command will work for Ubuntu.

[emmanuellekamwa]

All the solutions you proposed did not work for me. Anything else to propose?

[steveward]

@emmanuellekamwa are you encountering the could not resolve host error? Are you behind a firewall or proxy server? It would also be helpful to know the specific actions you have already taken to try and resolve the issue.

[emmanuellekamwa]

@steveward Yes I have that error and I am behind a firewall

[steveward]

@emmanuellekamwa you may need to reach out to someone who can assist with allowing GitHub Desktop access through your firewall. Unfortunately there isn't much we can do on our end about this error. Are you running any specific antivirus software? Is this a corporate machine?

[ayushshaz]

It worked for me when I used "service apache2 stop" ;-)

None of the solutions worked for me. Finally re-connecting my wifi did the trick.

[elias8808]

It shows me this error because I ran out of internet at home for a few hours. but I thought that SD was completely offline and now I realize that if there is no internet it does not work. Is there a way to fix this in case some other day you were without internet?

[niranjandasMM]

1. Try restarting your system and try again all these :

2. git config --global http.proxy http://proxyuser:proxypwd@proxy.server.com:8080

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

4. git clone https://github.com/niranjandasMM/TEST.git

[davik4life]

I encountered this same issue today for the first time and immediately noticed it had to do with my internet connectivity. I realized my internet router went off, which was the reason for the error. As soon as I went back online, the push command worked.

[alvinChristianto]

in my case its because windows defender public firewall.

i use wsl2 ubuntu 20 distro, usually i can push and fetch, but after some changes in host windows, wsl2 cant push and fetch. The ping github.com also fail. after some searching for issue, i try disable windows defender public firewall, and then try to do git commands and it works again.

[EduMRX]

Se você está enfrentando problemas de resolução de host no Kali Linux e precisa resolver o problema temporariamente, pode criar um script que ajuste as configurações do arquivo /etc/resolv.conf. Certifique-se de entender que esta é uma solução temporária, e você deve procurar corrigir o problema subjacente com as configurações de rede ou DNS em seu ambiente. Aqui está um exemplo de um script simples que você pode criar:

Crie um script chamado, por exemplo, fix_dns.sh:

**#!/bin/bash

# Backup do arquivo resolv.conf
sudo cp /etc/resolv.conf /etc/resolv.conf.backup

# Substitui as configurações do arquivo resolv.conf
echo "nameserver 8.8.8.8" | sudo tee /etc/resolv.conf
echo "nameserver 8.8.4.4" | sudo tee -a /etc/resolv.conf

# Mensagem informativa
echo "Configurações DNS temporárias aplicadas. Tente novamente."

# Exemplo de comando para clonar o repositório Git após aplicar as configurações
# git clone https://github.com/niranjandasMM/TEST.git/

# Restaure as configurações originais (opcional)
# sudo cp /etc/resolv.conf.backup /etc/resolv.conf**

Certifique-se de tornar o script executável com o comando:

chmod +x fix_dns.sh

Execute o script com:

sudo bash fix_dns.sh

Este script faz backup do arquivo resolv.conf original, substitui temporariamente as configurações com servidores DNS públicos do Google (8.8.8.8 e 8.8.4.4) e exibe uma mensagem informativa. Lembre-se de que isso é uma solução temporária e não corrige o problema subjacente na configuração do seu ambiente.

fix git clone unable resolve hosts name
vi /etc/hosts
in this and localhosts and localdomain like 127.0.0.1. and it's opposite section mention localhosts and localdomain
sudo service networking restart
and start git clone

[CodeNKoffee]

The error message you're seeing,fatal: unable to access 'https://github.com/....': Could not resolve host: github.com, suggests a DNS resolution issue, meaning your computer is unable to find the IP address associated with github.com. This can be due to various reasons such as network connectivity issues, DNS server problems, or local DNS cache issues. Here are a few steps you can take to troubleshoot and potentially resolve the issue:

1. Check your Internet connection:
   Ensure that your Mac is connected to the internet. You can try accessing other websites or pinging a well-known site.

ping -c 4 google.com

2. Flush your DNS cache:
   This can help if the issue is related to a corrupted or outdated DNS cache.

sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder

To anyone who is using git CMD over socks5 proxy:

if your computer failed to access github.com by git or curl command like next:

C:\Users\admin>ping github.com
Ping request could not find host github.com. Please check the name and try again.

C:\Users\admin>curl -v github.com
* Rebuilt URL to: github.com/
* Could not resolve host: github.com
* Closing connection 0
curl: (6) Could not resolve host: github.com

C:\Users\admin>curl -v github.com --proxy socks5://192.168.29.1:1080
* Rebuilt URL to: github.com/
*   Trying 192.168.29.1...
* TCP_NODELAY set
* SOCKS5 communication to github.com:80
* Could not resolve host: github.com
* Closing connection 0
curl: (6) Could not resolve host: github.com

and if you can get 301 redirect over a socks5 proxy:

# `20.205.243.166` is the IP of github.com, you can found it at https://docs.github.com/en/authentication/keeping-your-account-and-data-secure/about-githubs-ip-addresses
# `192.168.29.1:1080` is your socks5 proxy
C:\Users\admin>curl -v 20.205.243.166 --proxy socks5://192.168.29.1:1080
* Rebuilt URL to: 20.205.243.166/
*   Trying 192.168.29.1...
* TCP_NODELAY set
* SOCKS5 communication to 20.205.243.166:80
* SOCKS5 connect to IPv4 20.205.243.166 (locally resolved)
* SOCKS5 request granted.
* Connected to 192.168.29.1 (192.168.29.1) port 1080 (#0)
> GET / HTTP/1.1
> Host: 20.205.243.166
> User-Agent: curl/7.55.1
> Accept: */*
>
< HTTP/1.1 301 Moved Permanently
< Content-Length: 0
< Location: https://20.205.243.166/
<
* Connection #0 to host 192.168.29.1 left intact

it means that your computer failed to resolve DNS but your proxy socks5 works and you can use git over this proxy when configured properly.

using http:// or socks5h:// (not socks5://) will enable your git to access github.com

git config --global http.proxy http://192.168.29.1:8088   # use http proxy
git config --global https.proxy socks5h://192.168.29.1:1080   # or use socks5 proxy
git clone https://github.com/abhinavsingh/proxy.py
