how to resolve port 22 connection timeout

Question

ssh: connect to host bitbucket.org port 22: Connection timed out
fatal: Could not read from remote repository.

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

My firewalls are disabled and I still get connection time out. What should I do?

Solution

Looks like you have issues with the default SSH port and they could be avoided by using another port. This is a common issue.

Basically, you can use port 443 instead of 22.

• For Github, the answer is:

To set this in your ssh config, edit the file at ~/.ssh/config, and add this section:

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

• BitBucket: Answers below confirmed you can still do this even though it was supposed to be discontinued on June 15, 2011:

   Host bitbucket.org
    Hostname  altssh.bitbucket.org
    Port  443
  

• For Gitlab, the ssh config looks like this. Update the IdentityFile to match your local private key:

   Host gitlab.com
       Hostname altssh.gitlab.com
       User git
       Port 443
       PreferredAuthentications publickey
       IdentityFile ~/.ssh/gitlab
