Sonarr DNS Name Resolution Failure on Synology

sonarr

#1

All of the sudden my Sonarr container appears to be having DNS resolution failures.

An example from the Log is:

Failed to Update Scene Mappings: DNS Name Resolution Failure: ‘services.sonarr.tv

I tried manually setting the DNS in /etc/nsswitch.conf but it does not seem to matter. Not really sure how to troubleshoot this within the container since there isn’t much installed there in the way of utilities. Any ideas?

I have used the following command to create the container:

docker create \
  --name=sonarr \
  -e PUID=1029 \
  -e PGID=65537 \
  -e TZ=America/New_York \
  -p 8989:8989 \
  -v /volume1/docker/sonarr/config:/config \
  -v /volume1/docker/sonarr/tv:/tv \
  -v /volume1/docker/sonarr/downloads:/downloads \
  --restart unless-stopped \
  linuxserver/sonarr
