Game Bug Fix - Creatures Not Loading and Fighting Doesn't Start

I'm looking for a talented developer to identify and fix a persistent issue in my web browser game developed using PHP, HTML5, JS, Flash and MySQL. I am encountering a problem in my game that causes the creatures not to load to the hunting screen and the fight sequence to not start. The error message that may indicate the problem is in the proxy error log, but it could be something different. In fact, these files are already working files, but I need someone who is an expert on the necessary adjustments. This issue occurs every time I try to start the fight and there is a warning that the connection to the fight server has been lost. 2024/04/13 09:08:09 [error] 13606#0: *56 openat() "/var/www/vhosts/example.com./httpdocs/fproxy/req62347" failed (2: No such file or directory), client: [login to view URL], server:[login to view URL], request: "GET /fproxy/req62347?e65899e26ca04ccdd8b1d1aff11b3797_550416 HTTP/2.0", host: "[login to view URL]", referrer: "[login to view URL]" (plesk, Centos7) What an ideal freelancer should have: - Advanced proficiency in PHP, HTML5, JS, Flash, Cmake, C++ and MySQL - Extensive expertise in browser-based game development - Excellent bug fixing skills - Deep experience resolving cross-browser compatibility issues If you have the necessary skills and expertise, I would welcome your offer.
