Plexconnect suddenly won't connect

I have PMS running on my Mac with Yosemite 10.10.3. All systems go. Runs great on my iPad and iPhone in home local wifi. firecore Apple TV 2 5.3 jailbroken. Installed GitHub Plexconnect and was all running perfectly. Watched several TV show and a few movies over a few days. Remote Access is iffy. Sometimes it works other times it refuses to work. No biggy as found on the road the shows all show up when it’s working but all I get is a spinning circle never starts a show. Don’t really mind as it is mainly for at home over local wifi that I want it to work. Now it suddenly refuses to discover the PMS server. If I go and look on my Mac it shows under devices that the Apple TV connected say 2 minutes ago but no luck on the Apple TV itself. Any ideas to get it working again?
