pgadmin4 query tool always shows message not connected

Question

Q: How can I diagnose and correct problems with the Query tool connection.

Using pgAdmin4 1.0-rc1 to connect to a local host "PostgreSQL 9.5.3, compiled by Visual C++ build 18..."

In the browser pane I can connect and drill down to my schema. I use the context menu to select 'Query tool'. The editor shows the correct database@host:port in the editor header bar.

When I execute this sample query select 1 as first;

I get the message tab showing "Not connected to the server or the connection to the server has been closed.

instead of a simple grid showing first 1

Same message shows for any query, and the time it takes to come back with the message seems to be too long, especially since I'm using a localhost.

The same query works fine in phpPgAdmin.
