"An Error Occurred"

Infuse was working fine last night, but today I am getting “An Error Occurred” when trying to go into any media folders. I am using Plex as the server, and the Plex client is working. I am seeing the same InFuse error on both my Apple TV and IPad. I did restart everything to no avail. Plex version is Version and server is running Windows 10.

If I go into the Infuse library I see an additional error: “Indexing Failed for Plex Server”

I went in and deleted the Plex server connection and readded it and it is working now. (Strange)
