I'm also seeing the following a fair bit, which I've never seen in an error log. Do you have any idea what it could be?

client sent invalid header line: "~~~~~~~~~~~~~~~: ~~~~~~~~~~~~" while reading client request headers

Some proxies mask some headers, e.g. "Referer", X-Forwarded-For", this line may be "~~~~~~~~~~~~~~~: ~~~~~~~~~~~~" "X-Forwarded-For: ............"

By default nginx ignores such headers and logs the message, but it may silently pass them to backend if

ignore_invalid_headers off;
