Plex: Sorry, Infuse encountered an error while trying to connect

Good evening all,

I’m in a bit of a pickle here …
I’ve been using Infuse ( amongst other things ) as a client for two of my Plex servers both hosted on separate Synology NAS devices.

I’m using Infuse, with these two servers, on iPad’s, iPhone’s, Apple TV’s, and my MacBook.
Today whilst streaming all of a sudden my infuse displayed the error in the title.

All other devices on my network can still use infuse and connect, and my OS can still connect to the Plex services from my MacBook, only my Infuse appliction can’t seem to connect to Plex, SMB, …

I’ve already rebooted the clients, servers, etc.
When I removed the server from my library and went to add them again Infuse just says that my library’s are empty …

Anyone ever ran into similar issues or have advice?

Cheers!
