WEBDAV fails to upload during Veeam Backup

NetDrive version: 3.6.510
Windows/Mac Version: Windows 2012 R2

I’m using veeam B& R to backup offsite. I have a nas that is configured as a WebDAV server. My windows client has a drive mapped as a local drive using Netdrive 3. Everything seems to go fine but I keep getting error messages “Failed to upload to the WebDAV drive”.

I’m not sure why but the drive does have write access and I can write files to it.

Dear john

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 :

Sorry for the inconvenience it may caused.
