# Get a Secure Connection Error on some sites

tlsvpn

I am using Firefox version 37.0.2 with an ethernet connection at a university in Bangkok. I consider the university a network a hostile environment as the majority of the computers on this network are running counterfeit versions of Windows, and I have seen a lot of viruses on them.

When I try to visit https://technet.microsoft.com/en-us/sysinternals/bb963902.aspx (and other secure pages on microsoft.com), I get this error:

Secure Connection Failed
The connection to the server was reset while the page was loading.

Notes:

• I get no error when visiting the same url using Google Chrome v42.0.2311.135 or with Microsoft Internet Explorer v11.0.96
• If I connect to the Internet through a VPN (CyberGhost), I don't get the error at all.
• I have never added my university's security certificate to my Windows trusted store. I have checked certmgr and cannot see anything related to my university.

I would be really grateful if anyone can answer:

• Why only Firefox?
• Why does using a VPN fix it?
• If I don't trust the university network, would I be safer doing all my web browsing through a trusted VPN?
