V1.2 with behind nginx load balancer

Hi, I use V1.1.3 and nginx; it has not been successful,
I configured according to the documentation,
But it has been unsuccessful;
What should I pay attention to when configuring nginx?
Can you share the configuration of nginx?
Can I share the configuration of cong.json?
And auth.js… Thank you very much.
Or can you help me check it ?
