I have a host which is connected to internet via rather unreliable mobile hotspot. Connection is lost frequently for a few seconds or minutes and then recovered automatically. However, sometimes host becomes unreachable after connection issues. When I checked the log file I noticed that there is an error message "Internet-ID stopped - Stop command. Reason: Duplicated ID".
I have tried to generate a new Internet-ID but the problem still persist. I suspect that connection is lost for so brief moment that host loses connection but Internet-ID server doesn't notice that. When host connects to server to register itself a conflict occurs. Host recovers from this situation only be restarting the service.
We are not able to reproduce this issue in our environment. Could you please clarify, is there any antivirus software or firewalls installed on your Host machine? And how often do you get this "Duplicated ID" issue?
