[stunnel-users] Connection never completes

Thu May 23 00:21:53 CEST 2019

I am observing the same behavior Mario is seeing with STunnel 5.54 on
Windows Server 2012 R2 running as a client. In my case I am upgrading the
client side from STunnel 5.01. The client and server connected without
difficulty when both were at STunnel 5.01.
