Mount HD

I never had problems with mounting my music files hosted on a PC on the network. I always used the same configuration: \\Music, Cifs.
After returning to the factory settings to test a rebel plugin, it is not mounted but it reads the size of the directory and throws me this error:
"Error in adding network drive
(112): Host is down Refer to the mount.cifs (8) manual page (e.g. man mount.cifs) "
Any ideas?

I updated to the latest dev version and it was fixed.
Excuse me.
