ntfy behind Traefik proxy, loop causing rate-limit.

[oester]

I have ntfy behind a traefik proxy, and although I can subscribe, messages seem to go into a loop and time out with a rate limit. Here is my server.yml file: (redacted to not show actual domain):

base-url: "https://ntfy.xxx.org"
cache-file: "/var/cache/ntfy/cache.db"
attachment-cache-dir: "/var/cache/ntfy/attachments"
behind-proxy: true
upstream-base-url: "https://ntfy.xxx.org"

If send a message to the "test" topic, I see this in the log:

With debug, I see this in the log, with a loop of requests until it finally fails with rate-limit:

It's like the server is sending the request back to itself, endlessly. I can show you the traefik config, but it's pretty basic. Server is in docker with port 80 mapped to 4080 on the outside.

upstream-base-url needs to be https://ntfy.sh, not your own domain URL. I'm sorry this is so complicated and weird, but there's a description of the flow here: https://ntfy.sh/docs/config/#ios-instant-notifications

I'll make sure that you can never set upstream-base-url to the same value as base-url so this cannot happen.
