Sonarr/Radarr unable to connect

[spottedgravity]

Hi all,

I installed sabnzbd, radarr and sonarr in docker on a synology ds218+. Installed these following guidelines from drfrankenstein.

I got sabnzbd working, manually added an nzb and it downloaded. However when i want to add a download client(sabnzbd) in radarr/sonarr, I keep getting the following error message: "Test was aborted due to an error: Unable to connect to SABnzbd, please check your settings"

I checked a ton of times what i did wrong but cant figure it out.

I can provide a screenshot if needed. Also can provide logs from sonarr/radarr, but i'm not allowed to post links since i'm a newbie.

can anybody help me?

Do you maybe use HTTPS? Try without it.

Thanks safihre for the reply. Unfortunately i only use http to connect to them, so that cant be the issue.
Any further advice?

You run all the service in their own docker? Make sure to use the right URL that can be accessed internally on the Synology and externally.
What did you fill in Sonarr and SABnzbd for hostname and port?

@ safihre, yes i'm running them in their own docker.
someone on reddit suggested to use 172.17.0.1 for the hostname instead of 192.168.x.x and ever since it worked!
thanks for the help tho
