Hello.

Thank you for using NetDrive.

Could you attach debug log files to figure out what happened?

After setting the log level to VERBOSE, please reproduce the problem and send us the debug log file :

How to attach a log file

1. Change Log Level First, check your settings and change log level to VERBOSE. 1A. If you cannot login At your login screen: [image] Click SETTINGS at the lower right corner. Change Log level to VERBOSE and go back to login screen to apply the change: [image] 1B. If you can login Go to Settings: [image] Change log level to VERBOSE: [22] Set to DEBUG if you use old version because there is no VERBOSE log level. Go back to DRIVES screen. Changed log level takes effect when you leave …

There is no login related credential information in the log files.

Regards.

And If there is a dmp file in the path C:\ProgramData\NetDrive3\Dumps, please attach it too.

Regards.

Good day, jyyoon.

I was not able to replicate this issue, and it has not happened since I reported it. I’ll look for a dump file next time it happens. I found a few dump files from recent server reboots where the user did not stop the service, but nothing from the time of the issue.

This is not related to the service crash, but if it is of interest to you, here is what happens when the server reboots without stopping the service cleanly:
