## 4.6. Blinking message

### Problem:

The `Connection Status` in the Runtime window blinks between

        TCP Link to	dataserver established

and

        Socket has closed

### Cause:

The nserve program is not running.

### Solution:

Ensure that both qserve and nserve are running on the data server. Remember that qserve must be started first.

| The message will blink for a while, but if you don't close the Runtime window, the Socket will eventually time out, and stay closed for about 5 minutes.
