Hi. My SAS Enterpise Guide 4.3 (4.3.0.10196) is showing unknown error

A connection could not be made to the SAS Metadata Server but is required for the current operation. Please see your administrator.

It worked 2 days ago and now it is not connected.

Anyone knows how to fix it?

Thanks

You may want to talk to your Server Administrator.  You'd want to check that the Metadata Server is running on the target machine.  Sometimes when a machine is rebooted, the Metadata Server doesn't get re-started.

If the Metadata Server is running properly, you may need to check your port and firewall rules.
