GUI timeout when creating new SMB share

I am trying to create a new SMB share using the web gui. Version 7.1.2.2. Worked OK last week. This week every time I try to create a new share, I get Error 1 - no response from the server. I also tried this with IE and Chrome and logged in as root. Tried just waiting for a while, no luck there after an hour. I also get "no response from server" when using the command line.

Have no problem creating NFS exports. Anyone have any suggestions?
