using Firefox 81.0.2 (64-bit)
There was no ‘offer to save a new entry’ when logging into the above. (checked settings and feature is enabled).
Created a new KeePass DB entry for the above URL and tried logging in, the site did not detect that there was an entry and did not populate the sign in details at the above URL.
Other sites are still working with credentials being populated.
This is the first time I have tried the above URL (just updated keepassrpc to latest version, plugin shows as v184.108.40.206 in KeePass)
