BTH randomly stopped working. 7.14.3

I woke up today and the BTH wireguard connections from my admin/jumpbox to my router has stopped working.

Notice the existing BTH users list seems empty and trying to add another one is prompting the service is disabled.. when it is listed as enabled?

My “breakglass” standard wireguard VPN has allowed me to access winbox.

I have same problem. Came to work, but can not connect to my home BHT. I can ping the address, but it does not connect. I have 7.15 at home.

Well it seems all my BTH users were deleted. Had to add new one. Now I can connect. How could this happen? Maybe after I ugraded to 7.15?

Is it safe to disable/re-enable the BTH remotely? or should I physically be there and reboot/upgrade to 7.15 at the same time.
