Roon (1.2 build 161) server no longer sees Appletv's

Roon (1.2 build 161) server no longer sees Appletv’s (3rd gen) nor apple express, nor do apple iPad remotes see any remote libraries. They are all on same network according to iPad net analyzer app. Apple firewall is off. I have a UVERSE ARRIS NVG599 router connected via passthrough to an ASUS ac1900 router. The system worked up until 2 weeks or so ago when I decommissioned a 1st gen Apple TV and added a second 3rd gen ATV.

I have no issues with any of my Apple TV or APE’s with 161. My server is win10 so recheck your network connections prehaps using fing on a mobile device

iTunes is still able to stream to the same appletv that roon can’t see.

Any more suggestions as to why iTunes sees my one apple tv and one airport express and Roon now sees neither?
