Nabu Casa suddenly stopped working

Configuration

Hi all,

my nabu casa connection suddenly stopped working. I did nothing, its just not connecting through Nabu Casa anymore. When I check the options, it says I’m conencted to the Home Assistant Cloud with an valid subscription and I can normally access HA locally.

Anybody else with such problems?

Now it is working again. Stopped yesterday in the evening, and now it is back.

Same here now (May 2021, HA 2021.5.x).
