Removing old entries caused problem

Hello,
after a few weeks to building a Matter network based on the Sonoff Dongle the system was stable. Today I looked at the Matter server dashboard and saw around ten devices marked as offline. These were all old devices that had subsequently been re-added, because of this I removed all the Offline devices.

Node 39 was online, but after removing the other nodes (including two DUCTECH offline nodes) this one has now gone offline.

Checking via the entities shows that these cannot be updated:

Restarting the Matter service did not help.

What should I try next to get cover.bedroom_blind_top working again?

Maybe try going to the Matter Integration (not Server) and do a re-load on the Matter Integration.

in the end I removed the offiline nodes and re-paired them
