I know this isn't a unique question, but perhaps the manifesting situation is unique. Answers found elsewhere don't match what I believe are my circumstances.
I have a box hosting a few sites and, although there are no functional issues as far as I can tell, I see this message sprinkled throughout my Nginx error logs for almost every site. Everything I read points to a problem with my FastCGI params, specifically
SCRIPT_FILENAME, but my value seems to be inline with what's recommended:
fastcgi_param SCRIPT_FILENAME $request_filename;
Am I reading the wrong recommendations? I've also noticed that in some cases, but not all, the
host value in the log is one whose
A record points to the box, but isn't one that Nginx is listening for.
Any idea what might be going on? Is this error "expected" in the case of a 404, maybe?
