Node on Error in Dashboard Gateway: id is older than first tracked

The Dashboard showed OFFLINE

Node was stopped in did not automatically restart.

Restarted both node and gateway (on separate machines)

Both are running again, Node is sending and delivering Gateway seems to function as well except after some time

this message appears

id is older than first tracked

OFFLINE still was the message, could see some new rounds in the Dashboard although OFFLINE was shown

Now after 5 minutes the error message in the gateway has gone and Dashboard status is ONLINE
