Make sure your hostname for your static ip address is the first line in your /etc/hosts file. If the loopback 127.0.0.1 is the first line, you can get this error. Having said that, that error can be generated for many different reasons.
I'm not sure if this is the answer, but I was getting the same error -- it seems generic. I needed to enter the default URL for Studio, http://<servername>:19000. (Same as Workspace, just stop at the port number.)
