Check, if openHAB cloud Connector is online?

I am checking every 15 minutes. Since the 25th, there have been 11 timeouts (currently set at 4 seconds) but retrying the HTTP GET works. If I disabled Cloud Connector on my OpenHAB server, I see error 500 “OpenHAB is offline”. On October 24 between 08:15 and 09:05, I had a mix of error 500 and error 504 “Gateway Time-out” errors - for two cycles, stopping/restarting the Cloud Connector from my side did not resolve the problem. So far, I have not seen any cases where the retrieved random value did not expect the expected value.
