[Kalimeiro]

Hi,

We have a bug, not all times, on a Windows 11 Pro Client and VSS, see partial logs :

The server/client have latest build 3.1.4

The server is on Debian 12 BookWorm.

Hello,
OK, thank you, I think I need to add extra logging before that ERR= line.

Extra logging added in git master.

[grke]

Hello,

You could build it yourself, or wait for my next release, or you can download the one that I just built here:

https://burp.grke.org/downloads/test/burp-win64-installer-3.1.5.exe

Hi,

I have the same issue on one specific Windows 10 PC. Both client and server are running Burp version 2.4.0 and I tried your 3.1.5 test build on the problematic client. Unfortunately, I don't see more verbose logs.

Is it possible there is something wrong caused by the localization? I notice that both the original issue reporter and me seem to run Windows with french locales. The "error" is saying the operation succeeded, it doesn't make sense.

Log extract from client instead of from the server this time:

Sorry to spam, but something I found I forgot to report: rebooting the PC resolve the issue and Burp is able to backup again but only for short time before the issue come back again.

Hello,
It sounds like there is something wrong with your PC.
Maybe try looking in the Windows event logs?
