Some countries have what we call a global router "A large system that manages the outgoing connections to other countries". Sometimes they put blocks on certain IP Addresses or Countries.

What I would try is this, go get a free trial of a VPN or free one if you can, and attempt to connect to the server, after connecting via VPN, try again without it. If it works via VPN and not via a normal attempt, then it might be your router or your countries block policies.

I would suggest contacting your ISP, and asking them what the issue might be.
