Hello I’m new to OpenProject and have currently installed the 3.0 version on debian.

I try to connect a projekt with subversion.
I try https and svn uri but every try results in error 404.

Is additional software needed to connect to a repository?

This issue can be closed, we found the problem and solved it.

The probelm: Missing sll certificate!
The solution: Manually execute svn command (svn info [PATH…]) and accept the certificate permanently.
