I was experiencing the "Cannot connect to Zoom Rooms" error when I was trying to connect a Crestron TS-770 and a Logi Tap IP to a Windows Zoom Room installation on a Dell Optiplex. Everything was just supposed to work as told by tech support from Zoom and Crestron.

Turns out, there is an inbound firewall rule in Windows Defender firewall you have to create for zrairhost.exe at port 9090. By default, the inbound rule is only created for the ZoomRooms.exe at port 9090. But further investigation led to us seeing only zrairhost.exe LISTENING at port 9090. Creating that rule and restarting the computer automagically let the TS-770 connect. Controls all worked fine.

To Zoom, could you please fix this for future installations of Zoom Rooms on a Windows PC? Either fix the firewall rule or create another one specifically pointing to zrairhost.exe

I've installed latest downloadable app for Android to an android touch panel and I can connect it to the zoom room using the pairing code after I log in to zoom. But this Android panel should not require users to log in. We need the panel to connect with the pairing code.
I log in to zoom with admin account and when I try to choose a location, there is an error similar to "Version 5.4... cannot select..." or similar.
This is unexpected since the running app version is more like 10.17...
Is there a reason the downloadable app will not allow permanent pairing like by entering the key for the room rather than the pairing code?
In the past I linked an iPad to the room and it remained regisered all the time.
I wondered if there is a flag to launch the controller in a mode that is not user dependent on the android tablets.
Thanks for any advice.

We recently started having an issue with Video not working at all in Teams meetings. 

Started last week, but now it will not allow me to turn on video in any of our zoom rooms. everything for zoom is working just fine, but for whatever reason, the video will not turn on. I have a ticket in with our MSP. we have zoom rooms with Creston panels using  Intel NUC devices.

Our boardroom Zoom Rooms system has been automatically updated to version 6.0.7 (4157) , 64bit. Since then, far end participants are unable to hear the people in the boardroom. We have a Crestron professional AV system with Zoom Rooms installed on Windows PC appliance (NUC). I had to manually downgrade to version 5.17.9 (3926) as downgrading from device management from Zoom portal does not have this version.

I opened a ticket with support (request # TS1273108), but they are just useless, so hoping can find a solution here.

We have been using DTEN Me boards for a few years now but lately they have become quite unreliable eg disconnecting microphones and cameras at random times. After much too-ing and fro-ing DTEN are saying that this is a feature to avoid having the turn the board off for updates or something. As we teach using them for many hours at a time this is not ideal. There don't seem to be any real alternatives though? Can anyone suggest something as an alternative to a DTEN Me board? We're super frustrated!
