ssh connection timed out

Question

I am not able to ssh in git to github or bitbucket or gitlab.
I typically have the following error message: how can I avoid it?

========== output ============

ssh -T git@github.com -i ~/.ssh/id_rsa -v
OpenSSH_7.2p2 Ubuntu-4ubuntu2.2, OpenSSL 1.0.2g  1 Mar 2016

I suggest to first test connection with telnet: `telnet github.com 22`. If this test is successful, you can exclude a firewall and know that sshd is running. — Cyrus, Aug 05 '17 at 06:51
Don't worry, ssh questions (all 18K of them) are on topic, especially when they are related to Git, a tool used for development. — VonC, Aug 05 '17 at 07:38
@Cyrus it's not working telnet: Unable to connect to remote host: Connection timed out not only with github but also bitbucket & gitlab. — SARAVANAN SYR, Aug 05 '17 at 14:12
Pretty sure, your corporate firewall is blocking all outgoing traffic to ssh. Verify it with some other network. — acsrujan, Aug 05 '17 at 21:25

Kill the SSH process and restart it. It has solved me similar issues. I have found that multiple instances of SSH, in that case you have to kill them all.

This error message is typical when

the remote ssh daemon is not running (which is not the case here regarding GitHub, BitBucket or GitLab)
the local port 22 is blocked for outgoing connection (which is generally the case when working in enterprise: only http(s) is open, not ssh)

The OP confirms the ISP has blocked port 22.

See if you can use an https url instead:

cd /path/to/my/local/repo
git remote set-url origin https://github.com/<user>/<repo>

Note that with trystack, you might need to follow this gist

Click the Security Groups tab, click Edit Rules, and add a couple rules:

imcp, from port: -1, to port: -1, cidr: 0.0.0.0/0
tcp, from port: 22, to port: 22, cidr: your.ip.address.here/32

Ok, what is your OS, from which you are trying to connect with SSH to a remote server? – VonC Aug 05 '17 at 14:15
UBUNTU 16.04 LTS. using built in terminal and terminator for linux.ssh to trystack & pushing commits to github, bitbucket,gitlab. – SARAVANAN SYR Aug 05 '17 at 15:47
@SARAVANANSYR I have edited the answer with a step to follow specific to trystack: can you check it out? – VonC Aug 05 '17 at 21:06
