There is a very good reason why these messages have started to appear 
since 4.11.0, they didn't exist before that version ;-)

As to what the message means ?

I think it just means that a connection failed for some reason, such as 
the share doesn't exist or the user doesn't have the required 
permissions, but to be certain, perhaps the person who added the message 
could clarify this.
