Cannot connect to Audiobookshelf with the app

My YunoHost server

Description of my issue

I have Audiobookshelf installed and I’m using my own domain with a subdomain, signed with Letsencrypt. The installation works as expected in the browser but not in the app, I have tried booth https and http. In the browser, I have to log into YunoHost first before I can log into Audiobookshelf, can that have something to do with the app not working?

Add the app to vistors group

Tried that now but still getting the same errors.
