Yesterday i closed all open ports of the synology diskstation ( 5000, 8080 and 8443 ) and before restarting the diskstation there were again logfiles form eclipse. But after a complete shutdown and restart of the server including the restart of openhab and mosquitto in dockers my log file showed no strange log entries this morning and mobile access is still granted even with closed ports.So thank you for your comments and I’ll update this chat in one week telling if still the log entries are gone.
