I’m quit new to Linux so sorry in advance for asking stupid questions ;-).
I follow the instructions to install Quickbox from https://hoarding.me/ (on a Hetzner VPS). I can login through my domain and see the Quickbox dashboard :-). However, I then installed Sonarr and NZBget and both seem to install ok. Rebooted the server just in case and tried to start both. But I get a 503 error on both of them :-(. I read through the other topics on this but wasn’t able to find a solution. Hope somebody here can help out! Much appreciated!
