Does the Digi PortServer TS 2 support incoming SSL connections using the TCP Sockets port profile in TCP Server mode?

Does the Digi PortServer TS 2 support incoming SSL connections using the TCP Sockets port profile in TCP Server mode? The UI only displays a Telnet TCP Port (200X) and Raw TCP Port (210X). One of the manuals does mention a SSL port (260X) but only briefly. I tried establishing a SSL connection to port 2601, and it works. But when I establish a separate connection to 2602, both connections fail. I’m not sure if this is a problem with the software I’m using to connect or if I’m trying to do something that the PortServer doesn’t actually support. Can anyone confirm that the PortServer TS models actually support this? Thanks!
