When we start a transaction on port 9443 pageant (z/OS 2.2) immediately
returns the following message:
15.57.58 STC02568 BPXF024I (TCPIP) Oct 18 13:57:58 TTLS›50397229®: 15:57:58 TC
846 EZD1283I TTLS Event GRPID: 00000001 ENVID: 00000001 CONNID:

846 0000000000000000 00000000Ö
Wireshark shows that a packet arrived at the target, but without response
from the server. There is not inbound rule, only outbound. Should we have
an inbound one? I also suspect that the problem is with the TLS level.
there is only one rule in pageant for port 9443:
