This is either an ancient version or Sonarr or an even more ancient version of Radarr, time to upgrade.

That’s usually a good way to get banned from indexers. This forum is for Sonarr support though, not Radarr.

Hi Markus
thanks for the quick reply. Ancient? probably both are 4 or 5 years old i would say.

I have tried many times over the past 4 or 5 years to swap to my indexer, but it always fails.

does a radarr forum exist?
