godot-git-plugin: Error -17: the SSL certificate is invalid on linux

Using Garuda Linux with openssl-3.0.7-4, libxcrypt-4.4.33-1, git-2.39.0-1, and libgit2-1:1.5.0-2, Godot 4 beta 10. Using the repo with CLI works just fine.

The server is running Gitea 1.17.3, SSL by Let’s encrypt. Apache acts as reverse proxy with a subpath. Server’s git version is 2.30.2. The same repo was successfully tested on Windows 10, so that shouldn’t be a server issue.

Git LFS is used in the target repo, configured properly both on the server and locally.
