Windows 10: Unable to Connect to Specific Remote Resource Port 443 on Windows 10

Hi,I’m encountering an issue when trying to connect to a specific remote resource, kb.engineering.ualberta.ca, using Windows 10. The error message I receive is:"Resource kb.engineering.ualberta.ca is online but isn't responding to connection attempts. The remote computer isn’t responding to connections on port 443, possibly due to firewall or security policy settings, or because it might be temporarily unavailable."Here’s what I’ve tried so far:Attempted connection both within and outside of CanadaChecked the firewall settings on my computer, and Windows didn’t find any issuesTried connectin

TCP - Remote ports 80 and 443?

Under resource monitor > TCP connections, I've noticed quite a bit of activity on remote ports 80 and 443.

I decided to track several of these IP addresses and whilst some are expected (Microsoft, Amazon (Firefox)), there were a few which went to other mainly web hosting services. Is this normal and expected?

Is it just routing through?

 

The remote computer isn’t responding to connections on port 443

I get this issue only on one site, I used to be able to get to it now i can't for some reason.. I'm using windows 10 my ps4 and phone and laptop that has windows 7 can't get to that site as well.. It is a sign in area as i can get to other places on the
site..It has been like this for weeks..

resource (socialclub.rockstargames.com) is online but isn't responding to connection attempts.

The remote computer isn’t responding to connections on port 443, possibly due to firewall or security policy settings, or because it might be temporarily unavailable. Windows couldn’t find any problems with the firewall on your computer.

 

tcp connect to port 443 failed

I have checked the port 443 by powershell in win 10 by the following command:

"tnc hostname –port 443" (mention hostname of the computer)

but I got the “Fail” result how can I solve the problem that get the “True” result?

I was created Inbound rule for tcp&udp 443 and also Outbound rule for tcp&udp 443 in windows firewall

When the other person checked my system from remote she let me know that the port 443 is not open.
