Hello,
I am using Bitwarden on prem with a self signed certificate since aprox. 4 years without any problems.
After the latest Firefox update to 128 ESR (128.3.0 ESR) I got the following generic error while accessing the Bitwarden server webinterface:
SEC_ERROR_INADEQUATE_CERT_TYPE
Also the password manager firefox plugin does not work anymore on that same machine. The exception for the self signed cert is set in firefox trusted certificates. There is no problem accessing the webinterface on latest Edge including Edge Bitwarden plugin.
On another PC, I still have Firefox 115 ESR where the Webinterface and password manager plugin still work correctly.
All the server, plugins, browsers are up to date to the latest.
After a quick search for the mentioned error above I got as a possible cause the extended key usage in the certificate.
Do I need to reissue the self signed certificate without the option of extended key usage? Would this be possible?
Thanks for any help.
Regards,
Marc
