Looks like you have one and possibly two different problems here.
The "could not open .." appears to be a broken or missing package. Install it:
Code:
sudo apt install gvfs-backends
The other issue relates to a years long design flaw in gnome related to how it "browses" the network for hosts instead of "discovering" them.
If smb://192.168.x.x doesn't work address the server AND it's share explicitly: smb://192.168.x.x/share-name
Note: How wine affects any of this I do not know as I don't use it.
