Any syslog messages from the telnet server?
https://www.ibm.com/support/knowledgecenter/en/SSLTBW_2.3.0/
com.ibm.zos.v2r3.halz002/ip_mvs_log_system_messages.htm

Note that I've also sent an email to the vendor of our mainframe
TCP/IP software to see if they have heard of this before. Otherwise, yes,
I get the following syslog message on the mainframe side:


D2 0126 BSTT075E T0000002 T0000002 LUNAME NOT AVAIL IP=10.10.0.127
11:15:53


and the following syslst messages from the server:
