Hi All,
I can ssh to my VM with terminal etc. However my stunnel has something stopping the packet flow? What could be the problem and what should I check / troubleshoot:
client log file:

My VM is a linux server, on startup of stunnel I get this concerning message which might be the cause?
However, I checked and stunnel4:stunnel4 has permissions on the folder and psk file.
