Fresh Opnsense - Cannot open Web Gui

[elvinmammadov]

Hello,

I installed Opnsense 21.1, the web gui login only works in Internet Explorer. The other browsers give the following error. Do you know how to solve it? Thanks.

It looks like you're browser is trying to force an https connection while OPNsense is using http. Also, why are you using a release that is over a year old?

Thank you for your reply. Because, I see some people complaining bugs in the the latest versions. Is 22.1.2 release recommended?

It might be an initial issue with TLS 1.3 use. I haven't been able to locate the issue, lest of all able to reliably reproduce. It might not be the server's fault but again it's been impossible to replicate in a lab environment.

Normally it goes away when you restart the GUI on the command line:

# configctl webgui restart

Or do not use TLS 1.3. Same same but different.

It *looks like* some counter presented to the client / browser is zero which is being discarded on the other end. Once that counter has been incremented server-side it works for the client always, but the real question is if that "zero" value is bad, wrong or a misinterpretation of the situation.


Cheers,
Franco
