Mainframe - QWS3270 Connection Issue

17 April 2017

The Mainframe has encountered an issue with one of the security certificates.  As a result, users will not be able to log in using secure option of QWS3270 terminal emulation.  However, users may connect to the mainframe without the security option.  

Please use the following instructions to connect to the mainframe using ‘QWS3270 Secure’ without the secure option.

To do this with QWS3770 do the following;
1)    Edit your session parameters
2)    In the connections dropdown change the port to 23
3)    In the security panel un-check the security box
4)    Apply your changes
5)    Click OK
6)    Click connect
At this point you should be connected.
