I am running stunnel 5.04 for Windows on a Windows 2012 R2 instance. I have it working with SES, but after a while it just keeps timing out. I have to manually reload the configuration file to get it to start working again. What am I doing wrong?
Before reloading the configuration file it tries to connect 54.68.86.38, 54.68.197.46, and 54.213.178.250:

After reloading the configuration file it tries to connect 54.244.8.28:

As you see the DNS entry has been changed (your target service uses dynamic IP addresses). The solution is quite simple. All you need is to disallow caching the resolved IP addresses with "delay = yes".
