I had not tried that actually. I didn't even think of that.
Before seeing your last post I went and removed the docker container, manually deleted all the files I could from the AppData folder (everything except a file called keypairs that I did not have permission to delete, whatever that is) and re set up the container from scratch and that now seems to be working.
By working I mean that I am able to add and search for TV Series.
I have come across a new issue however with my freshly set up Sonarr: every time I search for a show it finds the show but when it passes it over to Deluge it shows as having a size of 0 KiB and hence does not download. I figured it is not an issue with Deluge as when I manually add a download to Deluge it shows the correct size and therefore downloads properly.
I have tried this both with the proxy entry on and off in Sonarr.
Any ideas would be much appreciated.
Cheers and thank you,
