Error: TrustFailure (Authentication failed, see inner exception)

If i try to use KeePass via Mono to and sync a file with WebDAV, i get the error message: *Error: TrustFailure (Authentication failed, see inner exception). The server is using a letsencrypt cert, in browser all works fine so far. According to an entry in KeePass Forum, on Debian, i should blacklist or remove /usr/share/ca-certificates/mozilla/DST_Root_CA_X3.crt and run update-ca-certificates and make sure that ca-certificates-mono is installed. On Manjaro, i have not found ca-certificates-mono package. Also DST_Root_CA_X3.crt is not found.

Any idea, what i can do?

Many thx. This is already installed. I have re-installed and tried again, but no luck.

Is KeePassXC an alternative for you?

Not really. I miss to many features there. Biggest issue is, that it doesn’t really sync with a remote database on a WebDAV share and I must mount the share locally, which is by far bot the same. I miss re-using custom field names, some auto-type-placeholders and sometimes it type a sequence not correctly. So sorry, but no, it’s not a alternative.
