I had the same issue, so first I tried all combinations with SMB// etc (like Greg on the 18. August 20) without success. By the way: in German I can edit the connections via ... > Speicher-Manager
Then I deleted the SMB connection and tried again from scratch ("+" > Neue Cloud Verbindung > LAN/SMB).
But this time I let Solid E. search the network for my PC and this took a while but found it.
I selected this connection in "Server-Details" put User and Password and now it works :)
This looks like a bug in Solid E. in that SMB-feature for me. Please fix :)
