Can’t see any logs. I have been investigating a problem which appears to affect servers that have a WAN IP address as the local IP address and access to the server gets lost when remote access is disabled. I need logs to confirm if it is the same problem
Assuming you have not disabled debug logging, please locate the logs folder and copy it out and zip the copy and attach. Please do that after restarting the server and waiting 5 minutes.
(If debug logging is disabled you will need to edit the Preferences.xml file to add it - lets check the logs first)
For location of the Logs directory, see
