ISP blocking Radarr? Running Radarr behing Gluetun

Hi!
I'm riding a very steep learning curve today, but now I'm running into a problem with Radarr.
While following the installation guide for YAMS today (btw amazing! Thank you!), I tried to set up Prowlarr and couldn't connect to any indexers. I got different error messages (can't reproduce now). I followed the guide of running Prowlarr behind Gluetun (https://yams.media/advanced/prowlarr-behind-vpn/) and that worked like a charm!
I finished the setup and wanted to try my first download, but I couldn't get any results in Radarr and Sonarr. Error: Invalid response received from SkyHook. Resource temporarily unavailable (skyhook.sonarr.tv:443).
Wannabe-smart as I am I did the same trick and ran Radarr behind Gluetun, and now I get all the results!
However, I now have to reconnect Prowlarr again. I tried replacing the yams network IP with my host IP, put there is a connection timeout. Any solution for this? I use Proton VPN Plus.

Thanks a ton it advance from this massive newb.

Hey @mfnewb!

That's weird, this is the first time I see Radarr being blocked by an ISP :?:

Now, the change you did works, but it removes the static IP for radarr. Can you try using radarr as the host? So the radarr server would be:

Code: Select all

radarr:7878

If it doesn't work, you'll have to do some custom networking in the dockerfile. Let's hope the hostname works in this context!

Another question, does Sonarr work?

Cheers!

Roger.

Wow I didn't expect a reply so quick! Thanks already!
I tried that, but I get:
"Unable to complete application test, cannot connect to Radarr. Name does not resolve (radarr:7878)"
Maybe I should add, I'm running AdGuard Home on my network, but switching in on and off doesn't change anything..

Sonarr has the same issues. (Search for 'the office' failed. Invalid response received from SkyHook. Resource temporarily unavailable (skyhook.sonarr.tv:443))

Oh, you're using Adguard!

Make sure Adguard is not blocking those domains. Open https://skyhook.sonarr.tv/ in your browser, you should see something like this:

If you don't, then Adguard might be blocking that domain.

Actually, I'm almost sure Adguard is blocking those domains:

I'm seeing {"status":"looks ok"}
Regardless of whether AdGuard is on or off.

Ok, that's super weird :shock:

Maybe it was down when you tested the first time? Try moving Sonarr/Radarr outside of the Gluetun network and trying again. Sorry I don't have a better advice, this is the first time I see this issue, it's super weird :|

Thanks for your help!
I only moved Radarr into Gluetun, I haven't changed Sonarr yet. So right now Radarr gets movie results, but I can't find shows in Sonarr. Prowlarr is connected to Sonarr, but I can't get Radarr connected.
In response to the reddit post, I tried to access /etc/docker/resolv.conf but that folder is empty :?

I'm completely stumped. I don't know what else to try :?

Are you sure you didn't edit anything else on your machine?

Alright, I managed to fix this. It was a DNS issue in the yams_network. I didn't know how to fix it, so I moved Sonarr, Radarr and Prowlarr to the bridge network in Portainer (very, very steep learning curve). Changed the IP addresses in Prowlarr to my localhost address. It works now! :)
Used yams check-vpn to verify that the qBittorrent traffic is still going though Gluetun.
