Huntarr Setup Auth Mode - Failed to fetch

[dataanh]

Just setting up a new instance of Huntarr. Here is my compose:

services: huntarr: image: huntarr/huntarr:latest container_name: huntarr ports: - "9705:9705" volumes: - /mnt/Volume/Apps/Portainer/Data/Huntarr:/config:rw environment: - TZ=Europe/Berlin - BASE_URL=/ restart: always

The setup-process is starting but in step "auth mode" i get always the error:
Failed to fetch

This error always displays with every login methode.

Any ideas?
