Error creating the share. (...or uses a self-signed certificate)

“Error creating the share: Sharing [SomeFolderName] failed, could not find @[someUserName], maybe the server is currently unreachable or uses a self-signed certificate.”

I am unable to share folders between users, not sure what is the problem. Is it just me seeing this?

My apologies I didn’t get back to you on this one, can you try now, I’ve adjusted some settings on the server.
