After restart the router rbfeeder does not connect.
Reloading OrangePi did not help.

I also got this error after reinstalling the OS (now i use armbiam bullseye on OrangePi too).
Apparently the error "Invalid sharing-key" it was solved by stopping the service
systemctl stop rbfeeder
And run only
rbfeeder
After that the error no longer appears.
Ah, I also have the same error you mentioned about the serial CPU, but that doesn't interfere with anything apparently.
