Hi @axiom88guru,
So far in my experience, such errors have always been from the Application side rather than NGINX. Check your Application, I can guarantee there will be a misconfiguration somewhere on it rather than with NGINX.
Other than that, I can’t give more suggestions just because I’m not sure what your setup is or the configuration of the app.
