I’m pretty sure AAs “workaround” was port based. As I recall, connecting to a VPN host over 443 used to work, then that stopped working. After that, UDP over port 53 worked for a while and, same as you, that stopped working a couple months back.
I haven’t found a combo that works anymore, and this never worked in their Panasonic equipment. I’m guessing they switched everything to either some random port or only allow listed IPs or domains for the initial connection. 😕
I think that happens when you launch Teams from Start. But that Teams icon is actually the link to the Old Teams with the New Teams having its own also new but separate icon somewhere else in the Start menu…
Because Microsoft.
