Problem webdav Synology

Hello everybody.
Sice many months (years) i used Netdrive for Webdav conexion to my Diskstation.
Few days ago it doesn´t work. The configuration is exactly the same. It says: CONNECTION ERROR
I tried with external IP too without success.

I have no idea where the problem is

Hello dolfoss

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 :

There is no credential information in the log files.

Or the following topic will be helpful.

Regards.
