Is there an existing issue for this?

I have searched the existing open and closed issues

Current Behavior

Searching for Artist name or via musicbrainz id is returning

Search for '<ArtistName / MusicbrainzID>' failed. Invalid response received from LidarrAPI. An error occurred while sending the request.
Search for '<ArtistName / MusicbrainzID>' failed. Unable to communicate with LidarrAPI.

Sonarr, Radarr works, this behaviour started about 2 weeks ago.
There were no network/hardware/software change during this period.

Expected Behavior

Return the searched artist and the ability to add it to the library.

Steps To Reproduce

Library
Add new
Search for artist
Error comes up
