After updating to the version 23 from 22 I started getting the error: Could not load comments. 520

So I used this mainly for the wiki function that I used for a personal work wiki and it ran perfectly for 2 or 3 months until I decided to update from version 22.x to 23.2 in November of last year when the AI feature came out and i want to see how it worked and it after updating I imedeately started getting this errors and the knowledge base articles sometimes fail to load and only load after the 2 or 3 try.

I suspect the new version requires a different nginx config but I can't figure it out.
At that time I only used one custom line in my Nginx Reverse Proxy Manager config, with ssl certificate from cloudflare:
real_ip_header CF-Connecting-IP;

This week i even rebuild everything from scratch and realized that only after proxying it did it start having the same issues, so im sure its something with the reverse proxy but I need some help with it.
I followed the info in the install guide and added everything to the config.

Youtrack version: 2023.3.24329
System OS: Unraid Docker
Current nginx config is:

real_ip_header CF-Connecting-IP;
add_header Access-Control-Request-Method '*';
add_header Access-Control-Request-Headers '*';
add_header Access-Control-Allow-Origin '*';
add_header Access-Control-Allow-Credentials '*';
add_header Access-Control-Expose-Headers '*';
add_header Access-Control-Max-Age '*';
add_header Access-Control-Allow-Methods '*';
add_header Access-Control-Allow-Headers '*';

       proxy_http_version 1.1;
       proxy_pass http://192.168.1.77:8766/contextPath/api/eventSourceBus;
   }

Thanks for any help.
