I don’t think it is related. Just just removed the address=127.0.0.1 parameter from server.xml and it is responding to requests, so I believe that is a red herring.
Weirdly, after fixing "My Activity Stream" just a stack trace, the server started responding to requests immediately. I don’t want to get my hopes up, but maybe there was a bad startup path that involved that problem. Only time and testing will tell.
