I am trying to connect to host server using putty (for SSH). In putty I enter my server's IP and port as 22 and when click 'open' get this error of connection abort and putty becomes inactive. I tried changing the putty settings as suggested here (PuTTY Network Error: Software caused connection abort) but still the issue remains.
I don't even see the prompt to enter login credentials, connection is refused prior to that.
Called the tech support, they are able to connect via putty and informed me to check with my ISP.
Not able to understand what the issue is. Please help!
