> In September of 2021, the content server for Massive Ads (http://madserver.net) started delivering blank content to anyone that requested it. Presumably, Microsoft shut down the service. Of course, this had the effect of knocking a few games offline that couldn’t understand the responses they were getting. I sent a few emails to Microsoft and they were helpful enough to refuse connections to the address. So as of now, you should be able to play SWAT 4 again.

Neat fix - presumably an empty response blew up the XML parser but ECONNREFUSED escapes to safer code?
