Hubitat Mesh feature: Protocol and Ports

I have several Vlans and need to know the appropriate broadcast ports needed to allow Hubitat to Hubitat meshing.

Something like
UDP Port(s) ?????
TCP Port(s)

This way I can allow the appropriate directed broadcasts for discovery and comms across the vlans, just need to know the protocol/ports.
Yes I could sniff this but I thought a direct question and answer is always clearer

Last I read, Hub Mesh used a local multicast address of 239.255.8.8 and port 45588. I believe the protocol is UDP only. Others can correct me if this information is no longer current.

EDIT: As of 2.3.4.138, Hub Mesh is TCP only (both protocols were added at some point since the above) over port 8083

Just for reference, not wanting to oost an old thread

As of 2.3.4.138, the mesh supports only TCP
