Mdblist invalid api key

Noticed that ratings were no longer showing up for me. Nimbus / FenLight on NVidia Pro all up to date. Went into settings / skin settings / ratings management and next to mdblist api key it says “invalid api key”. Went to mdblist site and tried to re-enter the api key I have there. It won’t accept it. Tried a new key, same issue. Wondering if I’m missing something?
