Form component and webhooks

Over the past few days, I have done everything I can to solve the following problem:
When I use the form component and use it under my local Servbay installation, the connection to my Zapier Zap works smoothly.
However, it does not work on my Ions(1und1) web space.
So I set up an AWS Lightsail instance and installed an Apache server on the Ubuntu (22.4) instance and configured it so that I have full control. I checked everything. The website works smoothly. Only the contact form always reports a submission error.
I compared the modules on the Apache server with the Apache server from Servbay and adjusted them. Still no success.

Now I’m at a loss. Maybe someone can give me a tip. The error message in the developer console is always the same 404. Is it a read/write permission issue? Or do I need a special Apache server config? Any suggestions are welcome. My internal DevOps team is already desperate. They pride themselves on solving every problem, and I’m scratching their self-confidence.

The website is otaliolab.com

Did you also install PHP??

Can you send us the form error log so we can take a look?

Details on how to do that below:

This is the Version installed:

Copyright (c) The PHP Group
Zend Engine v4.3.6, Copyright (c) Zend Technologies
with Zend OPcache v8.3.6, Copyright (c), by Zend Technologies

Hi Dan,
thanks for the reply.

Unfortunately, I am not receiving a log file in the directory /var/www/otaliolab.com/html/rw/elements/com.realmac.corepack/api
The directory is created and filled on the Servbay installation /logs. Unfortunately, this is not the case on my AWS - Lightsail instance. I suspect it is a permissions issue… but I have no idea what that could be. I can send you the log file from my local Servbay installation for documentation purposes. If that is helpful.

Here are the results I get in Chrome’s developer console. Maybe these will help with the analysis.

Sounds like something might be up with the server configuration. When I run the ?apicheck it doesn’t show a success or fail message.

What version of PHP are you running?

I’m cc’ing in @ben to see if he can help out!

As stated in an earlier post…it is v8.3.6
