Symptoms

Tuxedo 11gR1PS1 workstation client application, on OpenVMS, is failing to connect to a NonStop Tuxedo 8.0 workstation listener/handler.

Tuxedo GP_CAT and LIBWSC_CAT errors in client output when starting up workstation client application.
Output, with TMTRACE turned on, shows that tpchkauth() is being executed by the application when errors occur.

143843.TuxMachineName!?proc.xxxx.2070294208.-2: GP_CAT:1317: ERROR: Invalid attempt to use 40-bit or 56-bit encryption

143843.TuxMachineName!?proc.xxxx.2070294208.-2: TRACE:at: } tpchkauth = -1 [tperrno TPESYSTEM]

The appearance is that an encryption negotiation failure is occurring but the connection is never made and no encryption level information from the remote WSL/WSH could have been received.
