Help & Support

Hi all,

Sinds a couple of days im getting the errors:

I tried pinging the index servers from the command line and that works OK.
I am running Sonar in a Docker on an unRaid server and until june 6 i have had succesfull downloads via sonar, after june 6 nothing any more.

Does anybody have a clue what the problem is or do i need to kill this docker install and start fresh with sonar?

Greetings
Rob.

Try restarting Sonarr and the docker image, it looks like a DNS problem and unfortunately mono caches DNS results (not sure if it will cache a failed one or not though).

Restarting Sonarr and the whole server had no effect. I also found that SABnzbd could not find the newsserver so i deleted the Docker images for both and reinstalled them both.

All seems to be working great now, all missed series are coming in now, and also the problem of the two episodes that were not recognised has als been cleared.

Guess something went wrong in the docker system, but all is good again.

Thx for your reply @markus101.

You know what, this makes no sense at all… but it works. The instant I duplicated the container and re-added, it worked perfectly.

So weird

So it happened again, name resolution failures on the indexers, and also the same problems with sabnzbd.

Rebooting did not work this time to, so in stead of deleting the Sonar container i switched the network type to NONE saved the container went back in and set the network type back to bridged and saved again.

Started a search for the missing episodes and they are coming in again.

Hope some one can use this tip in the future.
