Same here. - If I only enter the IP, I get a "Network Error". - If I enter my IP with smb://xxx.xxx.xxx.xxx I get a "server not found" error.
Even like NoBloodyABCorD I cant enter my Username und Password, because the fields are greyed out.
In Pigasus VR Media Player my smb-Connection to this server works fine, but I prefere Skybox because the nice User Interface and no issues during playing movies.
So it will be cool, if you fix this bug.
Maybe an smb secure issue, because other smb-Connections from my raid station and Fritz-Box are well found and accessable.
My Hardware: iMac Catalina, Vers. 10.15.7
@NoBloodyABCorD Which hardware are you using?
