ssh: connect to host X.X.X.X port 22: Connection timed out

Question

I'm running a linux based (centos 6.5) VPS. I had no problem since yesterday that everything was fine . I was editing Iptables rules , trying to reject and allow some services and ports but suddenly I got disconnected from VPS and could not connect anymore. I Googled a lot and read many topics regarding this problem but none of them helped me.

I tried:

• Reinstalling sshserver and client
• Flushing Iptables, saving it and then restarting it
• Changing the port for ssh using from /etc/ssh/sshd_config file to sth else and then allowing this new port from iptables

but I still have the problem.

any help would be appreciated.

As we commented :

Put this rule : iptables -A INPUT -p tcp -m tcp --dport 22 -j ACCEPT
