Bug description

After installing the latest client, a certificate issue occurs telling that there seems to be an error with the certificate chain

Steps to reproduce

• Trying to connect to my Nextcloud
• Checking the Certificate: Okay (Let's Encrypt)
• Web works fine, no errors
• Connection-/certificate error when trying to connect to my instance

Expected behavior

Connecting the client like earlier versions without any issue after the initial connection/configuration dialog. Looking in the browser, the certificate appears to be valid and also the mobile Client (iOS) works without any problem.

Reinstall of the client fixed this for whatever reason.

Hi @OliverPifferi does the server use TLSv1.3? Seems very similar to #3974

Reinstall of the client fixed this for whatever reason.

That is strange but glad the issue was resolved :)
