Hi Community,
I am using OPNSence now for some years and never had serious problems before.
From this weekend on, the login to the gui/website isnt working anymore. When opening the url I got the error:
SSL_ERROR_NO_CYPHER_OVERLAP (firefox)
I tried also opera and IE - and getting also errors.
Does someone have an idea, what is going wrong and how this error can be fixed?
Thanks in advance and best regards!
Problem fixed:
I determined, that the certificate on my management host were expired. Fortunately I was able to connet to my firewall via ipad.
From there I was able to create a new internal root and sub ca as well as a new internal certificate. After creating these 3 things I have imported the root and sub ca certificates into my windows computer - and it works.
This guide/video helps me to solve the problem:

same problem here. Just tried to install opnsense to an alix board (nano download)
but for me the certificate is not expired. (at least examine the ssl with kse told me)
found the badass... it was bitdefender disabled SSL scan and the "normal SSL" error came up.
