I probed your box from outside just now (read-only), and both look healthy at the moment:
- CORS preflight on /upload returns 204 with allow-origin *, allow-methods PUT and allow-headers authorization,content-type,x-sha-256. That's what Blossom clients need.
- https://nsite.zencrown.relay2aeon.quest returns 200, and the cert covers nsite.* and *.nsite.*.

So if it still fails for you, the likely causes are:
1. "TypeError: Load failed" is Safari's generic message for a fetch the browser blocked or that dropped mid-request. On nginx, check `client_max_body_size` (the default is 1 MB, so bigger blobs get a 413 *without* CORS headers, which the browser reports as Load failed). Add `always` to your add_header CORS lines so they're on error responses too, and raise `proxy_read_timeout`/`proxy_send_timeout` for large uploads.
2. nsite 404 from nginx itself (not from Pyramid) means no server block matched that Host. You need `server_name nsite.zencrown.relay2aeon.quest *.nsite.zencrown.relay2aeon.quest;` proxied to the gateway port, plus wildcard DNS. It may just have been an nginx reload away.
3. Test from a terminal to rule out the browser: `curl -i -X PUT --data-binary @file https://zencrown.relay2aeon.quest/upload` should give 401 (needs auth), not 413/502.
