<![CDATA[Possible package configuration issue with bounce processing webhook endpoint]]>Hi,

according to the official Listmonk docs, there is an API endpoint for recording bounces.
See: Webhook API

But the response is 405 Not Allowed (nginx) – anonymized:

curl -X POST -k -u "admin:password" https://sub.domain.tld/webhooks/bounce \
    -H "Content-Type: application/json" \
    --data '{"email": "eample@listmonk.app", "campaign_uuid": "e8ad4fdb-52e3-4907-b6a3-1c89c7dcb67f", "source": "api_test", "type": "hard", "meta": "{\"additional\": \"info\"}}'

<html>
<head><title>405 Not Allowed</title></head>
<body>
<center><h1>405 Not Allowed</h1></center>
<hr><center>nginx</center>
</body>
</html>

You might notice that I had to use the -k flag to ignore SSL issues since that was the first response without ignoring SSL issues:

curl: (60) SSL certificate problem: self signed certificate
More details here: https://curl.se/docs/sslcerts.html

curl failed to verify the legitimacy of the server and therefore could not
establish a secure connection to it. To learn more about this situation and
how to fix it, please visit the web page mentioned above.

Anyone experiencing same issue?

If so, curl https://sub.domain.tld should work. Does that work ?

Correct – works as expected.

I somehow suspect the request is going to another app or something else. Listmonk doesn't use nginx, so I am not sure why you get a response from nginx...

Nevermind. In the meantime, I found the issue.. Wrong TLD. 🦆

I think you have to start here first. Are you able to visit Listmonnk on your browser without any certificate issue ? If so, curl https://sub.domain.tld should work. Does that work ?
