HTTP authentication - Docker compose installation

Hi everybody,
I’ve come to a dead end and need some guidance in the right direction.

My setup:
Raspberry Pi 3 Linux osmc 5.10.78-5-osmc
Docker Dynamic installation

Everything is up and the containers are running, but when I access the ttrss server I will get a basic http authentication. The default credentials like admin/password or the preconfigured accounts I’ve set in the .env file do not work. I also did not explicitly activate any http authentication. When I check the status of my nginx container the last output is the HTML code of the ttrss login page which I want to access but I cannot reach it via the browser.

Maybe this must be configured in nginx? Does anybody has a hint where I can read how to deactivate and/or set the credentials for this authentication? Did I miss a configuration during docker-compose?

Thanks in advance!

tt-rss doesn’t request http auth, it can accept the results if you enable a special plugin, that’s it. something in your setup is wrong.
