Cannot get any metadata for TV Shows

(I am running plex on MAC OS 10/11/6) I have all my TV Shows and Folders named correctly according to the plex naming conventions yet I cannot get any metadata such as posters to show in my library. I have the agents checked and in the correct orders. When I update or refresh my library nothing changes. I have quit the app multiple times and also checked if it was something to do with the two files in the plex application support folder (as some other users suggested in the previous forum posts) but these two files were not there and the only file was a Services.bundle file). I am alos unable to do a match lookup using the correct tv show name or IMDB show number. Please can someone help me with this!

There was a general issue with thetvdb, it should be fixed by now

Identified - We are currently experiencing connectivity issues with TheTVDB for our metadata servers. This will result in problems retrieving TV metadata for the majority of users. We’re actively working to resolve things and expect to see improvements throughout the day.
