Error HMS-0500-0500-0001-0007: what to do?

Today, when switching on my P1S on, it started to update to 01.08.02.00. So far, so good. But when trying to print out of Orca I got HMS-0500-0500-0001-0007. Recommendation is: update Orca. BUT: my Orca is up-to-date. That’s a good example of a deadlock.
And before you ask: yes, I reset the P21S to factory. To no avail.
Known issue?

[EDIT] After downgrading the device firmware to 01.08.01.00 it worked again.

My understanding is that this is due to the “MQTT command verification failed” added in 01.08.03.00beta/01.08.05.00. LAN Only Mode + Developer Mode works for my setup, but downgrading is probably a more flexible option for the time being.
