Cannot connect to ssh server owing to misconfigured firewall

[ploppy]

I am having trouble connecting to my ssh server. It responds with a lengthy error message about no network etc. but it is the last message that concerns me:

Sometimes, such troubles can be caused by a misconfigured firewall.

How can I check the firewall if I cannot connect to ssh? I am running plesk 11.5 control panel and CentOS 6. Is this something I can do from plesk?

I can see that the firewall in plesk is set to allow all for ssh, but I cannot see way to disable the firewall to test ssh connection. Can this be done from plesk?

It is driving me absolutely bananas and I would be grateful if someone could shed some light as to how I can proceed.

Many thanks for your help.

Hello,

First try to disable your plesk firewall and check your SSH connection Otherwise you will have to contact your DC to stop iptables on your server, Because you are facing this issues due to iptables OR any third party firewall which is installed on our server
