Configuration.yml file location openproject

Hello. We need to configure the https port openproject listens to in univention. There is no https port, only http assigned for it, and we cannot force it. It only has a port defined for port 80 http. I tried using virtual host but it errors as it sees it as only port 80. It has same port number for http and https, cannot change it

Any help much appreciated!

Enable https through Admin open project account - it adds its port to both default-000.config and default-ssl.conf - it sets itself in apache to only use one port for both http and https - weird but working solid
