When I added the Dreamland plugin, the gateway died. As it turns out, Spike found the error in the Dreamland plugin. I could never get an error log on the d2gs it find the error. He managed to. He informed me that he discovered the error and informed Kingpin where the error is. The error will likely explain why the TCP game also fails at my end. I am posting this as a thank you to Spike and also as a sign that the gateway might come back. If Kingpin fixes the error, I will turn the gateway back on. Hopefully Kingpin will do it sooner than later.
I will keep you informed as I learn more.
