Forum OpenACS Q&A: Response to Server won't serve anything once .tcl libraries loaded at startup.

Based on your access log files it appears that the ForceHostP/ set hostname xxx should have worked.

The log files I was interested in are at /usr/local/aolserver/log/server-???.log but they probably don't have anything interesting in them based on your access log files. make sure you kill all existing aolserver instances "killall nsd", and try again. perhaps you either didn't restart the server after changing the config files or, if you did, an old instance is still running somewhere.
