Now that it loaded again for me, I can see the /graphql endpoint. Caching GET requests to endpoints for a few minutes (or even just one minute) will likely suffice, given that the puzzle is the same for all users. If I am not overlooking anything, stats will lag behind for that period of time in the worst case. More info on how to configure nginx can be found on https://docs.nginx.com/nginx/admin-guide/content-cache/conte.... When a 502 error is served, images or bandwidth are usually not your problem but your backend that is too slow. In your case you probably only need `proxy_cache_path` to define the cache path, `proxy_cache` to specify the zone name you used with `proxy_cache_path`, and `proxy_cache_valid 200 302 1m;`.

this is super helpful, thanks
