在远程主机上运行的Xdebug：无法连接回客户端->超时

Question

Since two days I try to get my Xdebug configuration running without success what drives me crazy!

My setup

Client: Macbook Pro with PhpStorm

Xdebug is running on a remote server ( Ubuntu 18.04 ) in a Docker ( latest stable version ) container behind the jwilder/nginx proxy.

Xdebug runs on PHP 7.3.9, Xdebug version is 2.7.2

Xdebug Settings:

xdebug.remote_enable=1
xdebug.remote_host=host.docker.internal
xdebug.remode_mode=req
xdebug.remote_handler=dbgp
xdebug.remote_port=10000
xdebug.idekey=PHPSTORM
xdebug.remote_connect_back=1
xdebug.remote_autostart=1
xdebug.remote_log=/var/log/xdebug.log

The xdebug.remote_host is docker.host.internal because I copied my config file from my local xdebug.ini. On Mac you use this value. In this case xdebug.remote_host will be ignored because xdebug.remote_connect_back is on.

This is the phpinfo page (too big to display an actual image here).

phpinfo

This is the output in my xdebug log file

[17] Log opened at 2019-09-07 07:40:29
[17] I: Checking remote connect back address.
[17] I: Checking header 'HTTP_X_FORWARDED_FOR'.
[17] I: Remote address found, connecting to 178.203.235.46:10000.
[17] E: Time-out connecting to client (Waited: 200 ms). :-(

This is my remote Xdebug validation in PhpStorm:

Its seems like everything should run: PhpStorm is setup correctly ( listening on port 10000 ) - but its not!!!

What have i tried: almost everything. I used older Xdebug versions, other PHP versions... nothing. Always the timeout when Xdebug wants to connect to my client.

Also I disabled xdebug.remote_connect_back and used the HTTP_X_REAL_IP as xdebug.remote_host --> timeout.

Then I thought maybe its the nginx proxy. So I tried it without it -> same error: timeout.

What am I doing wrong?

I wrote this post a couple of years ago which might be helpful: https://medium.com/@pavlakis/setting-up-xdebug-with-docker-and-php-7-2-f5a6553cb956

In case the proxy you're using is giving you a different IP, try the following: https://github.com/phpminds/website/blob/master/docker.sh
