so I’ve tried adding rate-limit handeling in my nginx configuration which seemd to have broken things.
I’ll share 2 nginx configuration versions, the first one without the ratelimiting part which works fine and the second one with the ratelimit part added.
The Confiug with the ratelimit part added, causes this too many redirects error.

            if ($allowed_endpoint = 0) {
                return 405;

I have tried quite a bit myself like moving block around so that they correctly apply in order as i’m aware that nginx look for the first match and if it finds a hit, it don’t look future.
