使用Homestead和php-debug的Atom IDE和Xdebug Vagrant：无法使其暂停执行到断点并进行调试

Question

I try to make my Xdebug running inside a Homestead Vagrant VM to connect into the Atom IDE. So via vagrant ssh I created an SSH connection and typed the following commands:

xon
sudo nano /etc/php/7.2/fpm/conf.d/20-xdebug.ini

Based on that question I have put the following settings to 20-xdebug.ini:

zend_extension=xdebug.so
xdebug.remote_enable = 1
xdebug.remote_connect_back = 1
xdebug.remote_port = 9001
xdebug.max_nesting_level = 512
xdebug.remote_host= 10.0.2.2
xdebug.remote_handler=dbgp
xdebug.remote_mode=req
xdebug.remote_autostart=true

Then my Atom configuration is the following:

"*":
  "atom-autocomplete-php":
    autoloadPaths: [
      "vendor/autoload.php"
    ]
    binComposer: "/usr/bin/composer "
    binPhp: "/usr/bin/php"
    classMapFiles: [
      "vendor/composer/autoload_classmap.php"
    ]
    insertNewlinesForUseStatements: true
  "atom-package-deps":
    ignored: []
  core:
    telemetryConsent: "limited"
  editor:

  "exception-reporting":
    userId: "9f9c6aa7-2152-104d-a113-56d710236d00"
  linter: {}
  "linter-ui-default":
    panelHeight: 300
  "php-debug":
    DebugXDebugMessages: true
    currentPanelHeight: "357px"
    currentPanelMode: "bottom"
    currentPanelWidth: "493px"
    server:
      keepAlive: true
      protocolDebugging: true
      redirectStderr: true
      redirectStdout: true
      serverPort: 9001
    showWelcome: false
    xdebug:
      pathMaps: "[{\"remotePath\":\"/home/vagrant/code/\",\"localPath\":\"/home/pcmagas/Kwdikas/php/apps/ellakcy_member_app/\"}]"
  "tree-view":
    autoReveal: true
    hideVcsIgnoredFiles: true

And I configured my Firefox's "Xdebug Helper" plugin like that:

But when I place some breakpoint to my code the execution does not stop to them/ not shown. Also over my Homestead I ping into the IP that is getting connected back like that:

vagrant@ellakcy-member-app:/etc/php/7.2/fpm/conf.d$ ping 10.0.2.2
PING 10.0.2.2 (10.0.2.2) 56(84) bytes of data.
64 bytes from 10.0.2.2: icmp_seq=1 ttl=64 time=0.064 ms

^C^C
--- 10.0.2.2 ping statistics ---
6 packets transmitted, 6 received, 0% packet loss, t

Further investigation proves that the Homestead VM is able to get connected to my host via netcat (the command is running inside the VM):

nc -z -v -w5 10.0.2.2 9001
Connection to 10.0.2.2 9001 port [tcp/*] succeeded!

So what else I am missing/misconfigured and how I can figure out how to fix it?

Edit 1

Further investigation proved that the php-debug starts and ends the debug session without stopping to any breakpoint as PHP Console tells:

Do you know why suddenly the debug session even if it has some breakpoints is getting terminated?

Edit 2

I changed my xdebug settings into:

zend_extension=xdebug.so
xdebug.remote_enable = 1
xdebug.remote_connect_back = 1
xdebug.remote_port = 9091
xdebug.max_nesting_level = 1000
xdebug.remote_handler=dbgp
xdebug.remote_mode=req
xdebug.remote_autostart=true
xdebug.remote_log=/var/log/xdebug.log

Then I change the listening port into 9091. The ide key is changed into atom-xdebug but still I cannot make it stop to a breakpoint. Also when runnin gover cli cannot write into /var/log/xdebug.log. Should I generate it manually?

Also I tried to enforce a breakpoint with xdebug_break() still no result.

Also my path mappings are:

[{"remotePath":"/home/vagrant/code/","localPath":"/home/pcmagas/Kwdikas/php/apps/ellakcy_member_app/"}]

And my local path is consisted of these files:

The project is written on symfony 3.4 as well.

In order for the atom to work with vagrant you should use the following xdebug settings:

zend_extension=xdebug.so
xdebug.remote_enable = 1
xdebug.remote_connect_back = 0
xdebug.remote_host=10.0.2.2
xdebug.remote_port = 9091
xdebug.max_nesting_level = 1000
xdebug.remote_handler=dbgp
xdebug.remote_mode=req
xdebug.remote_autostart=true
xdebug.remote_log=xdebug.log

Keep in mind with typos eg. xdebuf also in order for the atom editor to manage correctly the path use the following mapping:

[{"remotePath":"/home/vagrant/code/","localPath":"^local_project_root^"}]

Where ^local_project_root^ is the top-level folder containing the whole source code (in your case where ellakcy_member_app is located).

Also uncheck these options as well as the image shows:

In makes the atom not to work properly on breakpoints if checked. In case you have heaps of projects then remove them from your tree view and ensure you keep only one. You can add them later and continue working.
