Outgoing Webhook not working from Wordpress

[prononext]

Dear Caddy Community,

I have wordpress running behind caddy and want to use a html form to call a webhook outside of the container.

Sadly either html form and elementor based forms do not fire the webhook successul.

I tested the webhook via postman and it works fine.
Is caddy somehow blocking outgoing webhooks or do I need to make a extra setting to get it working?

Have a nice day.

Here is my Caddyfile:

{
email mail@example.com
}
example.com {
root * /var/www/html
encode gzip
php_fastcgi wordpress:9000
file_server
}

There is one repeating error on the caddy docker container, but it is not especially linked to that webhook problem, as its not coming up when fireing the webhook:

{“level”:“error”,“ts”:1664973005.9915617,“logger”:“http.handlers.reverse_proxy”,“msg”:“aborting with incomplete response”,“error”:“http2: stream closed”}

Thats the caddy docker-compose used:

caddy:
image: caddy:${CADDY_VERSION_TAG}
restart: unless-stopped
ports:
- “80:80”
- “443:443”
volumes:
- ${CADDY_DATA_FOLDER}/Caddyfile:/etc/caddy/Caddyfile
- ${CADDY_DATA_FOLDER}/data:/data
- ${CADDY_DATA_FOLDER}/config:/config
- ${WORDPRESS_DATA_FOLDER}:/var/www/html
links:
- wordpress
- php-fpm

I hope someone can help.

Hi, uhm, that’s still not the help topic template.

We still don’t understand your problem nor your setup.

ye, you can just ignore that error. That one has nothing to do with your actual problem.

Since you are talking about some html form, consider looking into your browsers console/network tab and look out for any errors there.

Could you please fill out the help topic template?
Also, it might make things easier if you just post your website, the url to one of such html form you are having problems with and your working postman example.

No.
