If the connection process fails when you attempt to exit or reconnect to an EXTRA!

If this error occurs when you are attempting to connect, reconnect, or close an EXTRA! session, you may be able to resolve the problem by adjusting the EXTRA! reconnect parameters.

To resolve this issue:

1. In EXTRA! X-treme, click Options > Settings.
2. Under Categories, select Connection.
3. On the General tab, adjust the Number of retries and Delay between hosts settings to suit your network environment. We suggest that you start with these settings and adjust accordingly:

• increase the Number of retries to 3
• decrease the Delay between hosts (secs) to 1

4. Click Edit.
5. In the Configure Connection dialog box, select the Auto Reconnect check box.

6. Click OK > Apply > OK.

A 510 error in a TN3270/E session is a generic failure to connect error.
