Someone on Iran is unable to connect to my service which is hosted on a server in the U.S. It seems like most other services work for them fine but mine does not.
I asked them to ping the server and the request timed out.
Also I VPN'ed into UAE and South Africa and was able to establish a connection without a problem.
Does anyone have any idea why this might not be working? I'm actively communicating with them so clearly their internet does work. Do certain countries like Iran have firewalls?
Thank you.
