1. If you see error code 500. It means that some server error has occured. So you need to check your server error log to determine what thing that cause the problem.

2. In your case. I got it.
Maybe because you expose your docker container to listen on port 8000.
So your 8081 (XAMPP) site can easily connect to it.
But from docker container itself. Certainly, it run in its virtual docker bridge network, and if you try to connect to localhost:8081. Your container doesn’t see anything running on 8081 port because “localhost” now means itself (not your “localhost” of your host machine).

So what you have to do is you have to change in the sync post plugin setting in docker site from “localhost:8081” to “host.docker.internal:8081”. I think it will work.

Yes, I solved.
Please check your Chrome debug tool, in the Network tab, you will see 500 error after saving a post.

If I create a new post in site :8080, no error but nothing changed ??
When I update “Hello world” post then check Network log, It is a 500 error from POST request to mydomain.com:8080/wp-admin/post.php?post=1&action=edit&meta-box-loader=1&meta-box-loader-nonce=82860aa7a4&_locale=user
