Not sure if this is our problem, but after setting log level to debug we noticed this in the error_log. Not sure how to interpret what is happening. It looks like the fcgi connection to php-fpm is being declined initially, then it is successful. But I am not sure. Is this refusing to execute the php command? Thanks
