Debian 11, Client v3.0.0.9215 SSL Usertrust RSA cannot find local certificate

Expected behaviour

Connect to server using the new client version

Actual behaviour

The client does not accept the certificate issued by Comodo CA and USERTrust RSA in its chain.
Version 2.11.1 does not have this issue

Steps to reproduce

  1. Update to the latest clientversion on debian (in my case)
  2. Try to connect to a server using a Comodo certificate

Server configuration

Operating system: Debian 11

Web server: Apache / Haproxy

Database: MySQL

PHP version: 7.4

ownCloud version: 10

Client configuration

Client version:

Operating system: Debian 11

OS language: DE,EN

Qt version used by client package (Linux only, see also Settings dialog): 5.15.2

Client package (From ownCloud or distro) (Linux only): Owncloud


No logs produced when trying to login, just the ssl error dialog appears

Could you share the server URL?

No sorry, I don’t want to publicly share our corporate cloud url to the web. But a ssllabs test resulted in an A+ with no chain issues. Everything, everywhere works except the new client.

Updated on Mac OS today where it works flawlessly from the start using the same server.
Tried in two Debian machines and still no luck

Got it to work now by removing 0\General\CACertificates from owncloud.cfg
