I have a server that is acessible by some networks but not by others.
I tried here in my PC and it won't connect, but it still shows me the certificate warning.
After clicking to enter despite the warning, it keeps trying to establish secure conection and it gives me the error ERR_TIMED_OUT after a few minutes.
I tried connecting to https://mail.server.com:7071/ and to https://mail.server.com:443/.
In other hand, I managed to connect to https://mail.server.com:443/ another network that I have access to. But to https://mail.server.com:7071/, it only gave me a blank page with some blue borders.
My firewalls are not blocking anything and I can NMAP all the open ports.
In my network it gives me the timeout error, but in my other network (other PC too) it works ok to port 443 but not to 7071.
What might be causing this? SSL certificate maybe?
How can I check it?
Thank you already.
