Solution 1

This solved my problem:

http version:

git config --global --unset http.proxy

https version:

git config --global --unset https.proxy

Solution 2

In Windows, if you've any third party firewall (or internet activity monitor) installed, then configure them to allow your client to access outside connection.

If there aren't any 3rd part firewallls, then go to control panel, search for firewall. Inside the firewall panel, select Add a new exception (or similar option). Allow the git client both inbound and outbound access.

Solution 3

I recomend you to switch to ssh.

You can get github ssh link from same place where https one. Then you just have to generate/add your ssh key to github profile. And that's it.

I started using SO in 2014 during my first development job in C#. Ever since I have been reading and learning a lot from SO. I am person with great hopes in Entrepreneurship but not forgetting the development skills that I have learned so far and still learning. I always am open to opportunities to meet people and learn new things. I always love the moment when I can think, "I would have never thought about it this way". Technology and people never cease to amaze me.

I am trying to push files to my remote repository from my local repository and I see this

fatal error : fatal: unable to access 'https://github.com/vinivasundharan/abcd.git/': Couldn't resolve host 'github.com'

My computer is not using any Proxy because I have seen methods to resolve the issue when Proxy is being used.

I have tried the solutions from this and this. But both doesn't seem to help. My system has an active internet connection using Windows 7.

UPDATE

git config -l returns the following. I had to post it because I do not what exaclty this means
```
core.symlinks=false
core.autocrlf=true
color.diff=auto
color.status=auto
color.branch=auto
color.interactive=true

EDIT

Just to make sure that i have followed the steps to Upload the file to GitHub check the attached image to see the steps i have followed.

  Have you configured/changed your SSL settings?

  Does git config -l returns lines with 'proxy' in them?
- Vini over 8 years
  
  i haven't changed any SSL settings

  @VonC: check the updated question. I have added what it returned when i executed the git config-l

  It seems more like a DNS issue. Does ping github.com work from the command prompt? If not, the problem is with your network/network settings.

  @jszakmeister : You are right. ping doesnt work. But it doesnt work for google.com either. It keeps on showing Request timed out What change could be made to get it working. If there is a dns issue will i be able to access websites from my system?

  Hard to say--and StackOverflow isn't really the place for the answer. I don't run Windows these days (I'm a Linux/OS X guy--I abandoned Windows at home some time in 2001). The things I would check are that you are getting a valid ip address and that a valid DNS server is being assigned (you should be able to ping whatever address is being provided). I can't tell you how to fix any of it--many problems are very specific to an environment. And no, if ping github.com and ping google.com are failing to resolve the ip address, you will not likely be able to access other websites.

  Do you think i should migrate the question to another SE site? But i am able to access all websites. But the ping doesnt work. :(

  can you clone again that repo? (and try and push from the new clone?). Also, what does a set GIT_CURL_VERBOSE=1; git push returns?
- Vini over 8 years
  
  @VonC : it returns the usual warning that i get when tryin to use git push instead of git push origin master

  @ViniVasundharan Were you able to clone that repo? (in a new local folder)
- Vini over 8 years
  
  @VonC: When I try using git clone https://github.com/vinivasundharan/testnew1.git it shows couldnt resolve host. I can`t clone from the remote repository to the desktop as well. It fails as well.
- VonC over 8 years
  
  OK. export GIT_CURL_VERBOSE=1: after that a git clone is supposed to show a bit more. But if it shows only Couldn't resolve host 'github.com', then try the same from a CMD (not a bash session)

  Ok i get the fatal error again. I really do not know how i could do the same in a cmd. I tried executing the commands from the folder where the local git repository is saved. But it doesn't identify any of the git commands.

I do not have access tot he firewall settings in my system . :( Maybe it is possible that that is the issue. So it ends up in such a way that I will not be able to use github.

I am sorry I cant accept this as the answer as I could never check if this solution would achieve what I am looking for..
