Error description
Explorer fails to establish a connection to a NIST SP800-131A compliant host system. The Explorer Error Log shows the following message: IZE0106E Connect failed with error "Received fatal alert: protocol_version" (host:port)
Local fix
The problem can be circumvented by choosing TLSv1.2 manually from the Explorer certificate management preferences.
Problem summary
Explorer can use a variety of protocols to establish a connection with a remote host. The protocol used can be selected in the Explorer 'Certificate managment' preferences. If '-default-' is selected, Explorer will communicate with the remote host to choose the best protocol each time a session is establised. If this negotiation results in certain TLS protocols being chosen, the connection may fail with message: IZE0106E Connect failed with error "Received fatal alert: protocol_version" (host:port) TLS V1.2 must be used to comply with NIST SP800-131A. Additional Keywords: PM97207
Problem conclusion
Explorer has been changed to ensure that a connection can be established over TLSv1, TLSv1.1, and TLSv1.2 when the default connection settings are in use. This fix will be made available in Version 2.1.0.3 of the IBM Explorer for z/OS, which will be included in Version 5.1.1.3 of the CICS Explorer.
