Hey people outside,
my "Nextcloud Desktop" on Windows complains about the Let's Encrypt certificate of my Nextcloud Server. The Debian workstations don't have any problem.
I already renewed the certificate on the server, but still no success.
Also the expiration date of the shown certificate is different from all certificates in the Chain of the server (vilya.maxmue.eu).
Does anybody have a clue what could be the problem (except that it is Windows xD)?
In the certmgr.msc, I didn't find anything related to this server except for certificate for "DSR Root CA X3" which expired on 2021-09-30. I downloaded an updated list of root certificates with 'certutil.exe -generateSSTFromWU roots.sst' but there was no updated version.
For now, I imported the Server certificate itself into the certmanager.
