Source Code Analysis for Disconnect Issues

I need an experienced developer to analyze C/C++ source code on GitHub. I am experiencing client-side disconnects due to custom server-side flags, specifically impacting network communication. The application will simply open a Windows notification box saying invalid server. My goal is to either not check for the flags or return an acceptable flag back to the program.

I have tried using Windsurf and various LLMs to try to fix this issue myself, but this is beyond my abilities.

Key requirements:
- Expertise in C/C++
- Experience with network protocols and troubleshooting
- Familiarity with GitHub for code review
- Ability to diagnose issues related to server-side flags

Ideal skills:
- Strong background in network programming
- Problem-solving and analytical skills
- Previous experience with similar issues

Your analysis should identify the root cause and suggest potential fixes.
