[Solved] Myopenhab connection request timing out

I’m observing connection problems to my openHAB instance via myopenhab.org. Account is ONLINE
A connection request via the webpage to my dashboard ends with a “504 Gateway Timeout”.
Secret and UUID are untouched and did work yesterday.

Connection via LAN is working, openHAB logs don’t show the external request.
Status.openhab.org is reporting no problems.
Sending a mesage via myopenHAB.org to a smartphone ( not on LAN!) is working

Anybody else observing the same?

[Edit:] A reconnect to the myopenHAB server (reinstall binding or bundle:restart) fixed the problem.
