Server Unreachable on all devices

Hi

On update to 1.3.4.3285 none of my devices (Roku and iOS app) can see my server. Locally on the Mac thats running the server I can access it but everything else just flags Unreachable.

I have signed in and out, deleted the server, re-installed. tried everything I can think of.

Nothing has changed on my local network. No other settings were changed. Security setting is on preferred.

Please help!!
