Github connect to host github.com port 22: Operation timed out

Question

I suddenly started getting the following error message while attempting to push or pull:

ssh: connect to host github.com port 22: Operation timed out
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

How can I check If I have the "correct access rights"? I've been working on this repository for quite some time and never had issues.

What am I doing wrong?

Answer 1

Don't know if someone still needs a solution to this. Went through the same problem and I found a solution with the link below.

Create or edit ~/.ssh/config and append the following:

Host github.com
  Hostname ssh.github.com
  Port 443

Answer 2

我遇到了同样的问题，并通过从~/.ssh/known_hosts文件中删除 github 条目来修复它。
