Everything is set up following your guides. I have had to put prowlarr behind a VPN. I check all the indexers and they are all working with green ticks.
Radarr and Sonarr are connected to prowlarr but don't seem to be working. When I check the indexers, I get this message:-
"Unable to connect to indexer, please check your DNS settings and ensure IPv6 is working or disabled. Name does not resolve (prowlarr:9696)" for them all. I have not changed anything.
