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.

Thx. That’s what I did. But still unsatisfactory. I’ll mark it a solution, though it is not really one.

Yeah Bambu’s been getting really into locking people out after years of exploiting the good will of the open source community.

It sucks but they seem determined.
