OK so something I forgot about since it has been so long since I got my own for Fanart.tv There is a personal API key you can get to make it work correctly. This does involve making a free account at there and generating a key.
- go to https://fanart.tv/get-an-api-key/ Create a free account and generate a personal API key
- In the fanart.tv agent settings press the gear icon on the right and enter your key.
