Why am I getting many " Secure Connection Failed" errors, often for my workplace at SJSU.edu?
I've never had Secure Connection Failed warnings before, but now I am getting them often. I don't want to stop using Firefox, but it seems I can get to these sites via other browsers.

Yeah this is device specific, the cryptic error code basically means that "all possible combinations have been exhausted" when trying to establish a secure connection, but since the site(s) otherwise work it must be some kind of a "middlebox" (usually a security solution, either software on–device, or hardware in lieu of networking gear and its features), that intervenes and ends up making the connection not feasible (no overlap of protocols etc. — something that's not frequent on today's internet, esp. for maintained systems with major public traffic).
So you're unable to open https://sjsuone.sjsu.edu/sjsuone/ or even https://sjsuone.sjsu.edu/ with these same kinds of error on anything on that host?
Does anything improve if you change around any of your "DNS over HTTPS" preferences in Firefox Settings (turning it off, on, or changing providers), or connecting via the built–in VPN if you have one available, to try to route you via a different method?
(Can you restart all your routers, modems and other networking gear to rule out any connectivity wrinkles as well?) — if you have a mobile device you could use to tether the desktop to and use its cellular data perhaps, to try to circumvent the existing connection, is there any difference?

The reason will be in the "advanced" section if you can expand any of the errors, and share what's included there, any errors codes, certificate details etc.
Here is the whole message:
Secure Connection Failed
The page you are trying to view cannot be shown because the authenticity of the received data could not be verified. What can you do about it?
The issue is most likely with the website, and there is nothing you can do to resolve it. You can notify the website’s administrator about the problem.
Error Code: PR_END_OF_FILE_ERROR
That sounds like a firewall/antivirus/VPN or other security software (or even networking hardware) is trying to decrypt and re–sign the secure connections for you. See the section support.mozilla.org/en-US/kb/error-codes-secure-websites#w_check-your-antivirus-settings if any of the vendors there sound familiar.
If any of the domains you're having issues with are publicly available, feel free to share a few of the addresses here as well, so somebody can confirm whether it's otherwise working in general.
The problem does seem to be the homepage of the SJSU One login. Also, it seems to be specific to my desktop computer and not my laptop. I am not using any of the antivirus apps listed in your link. I can't see any settings in Windows Firewall that would help. I have contacted the IT department at SJSU.edu about the problem, but in the meantime am not sure how to determine what might be wrong.

Thank you. I turned DNS off and back on. Problem solved. Many thanks!
