V2 throws `Cannot GET //private/config`

My version of HedgeDoc is: 2.0.0-alpha.2

What I expected to happen: a successfull start

What actually happened: the Cannot GET //private/config back-end error is thrown

I already tried:

  • making sure that HD_BASE_URL is properly set ;
  • asking for support on Matrix, mentioning I’m using Apache as reverse proxy and followed the instructions at docs.hedgedoc.dev for setting up the Docker Compose and Apache virtual host files.
