On CoreELEC not connect to source after reboot

[xdub]

On CoreELEC version 9.2.2, the sftp connection stops working after the device is rebooted.
If I don't delete the passwords.xml file, I can't even use the same user for a manual connection.
Here are my config files:
mediasources.xml
sources.xml
passwords.xml - The file is created each time I reconnect.
After rebooting the log for each file reports:
