I keep getting "The Server.....is unavailable" lately. Anyone else having this?

Hi and Happy New Year to everyone.
Recently I keep getting :The Server.... is unavailable" when I try to log in.
I haven't changed anything and I've tried both directly from my iMac and via the Plex web site.
The Plex web site says I'm logged in but when I go to launch I get "The Server...is Unavailable" message.
This is from the error log -
"type": "log:message",
"level": 4,
"message": "[Connections] Retrying server events connection for (I removed the name ) iMac in 4 seconds",
"time": "2017-01-02T14:17:43.211Z"
},
