<Install debugger moduleconnection to the client ... not allowed message>
Last updated: Thu, 25 Feb 2010

PHP Debugging session failed to start with the message: "failed to connect to the client address <address>"

This is the set of instructions to troubleshoot and fix the communications between dbg - php debugger and PhpED - PHP IDE.

Why am I seeing this message?

You may see this message if the server side dbg module can not communicate to the machine with PhpED. This may happen due to several reasons:
  • Firewall on the dbg server or on the client PhpED machine or on both is not allowing the communications to go through
  • There a network router between the client PhpED machine and the server and this router is not forwarding dbg communications to PhpED's DbgListener

What can I do to troubleshoot this issue?

To check the communication between dbg and PhpED,
  • If dbg and PhpED are installed on the same network or there is no SSH tunneling setup between their machines please follow the instructions here
  • If dbg and PhpED are installed on the different networks and there is SSH tunneling setup between their machines please follow the instructions here

How do I fix it?

  • If your server with dbg and PhpED client machines are on the same network or on different networks not using SSH for communications, you will find the information how to fix it here
  • If your server with php debugger and PhpED - PHP IDE client machines are on different networks using SSH for communications please follow the instructions in for setting up php debugging over SSH

I think I fixed it. How do I make sure that it is working?

You can try to start the debugging session again or follow the troubleshooting instructions:
  • If dbg and PhpED are installed on the same network or there is no SSH tunneling setup between their machines please follow the instructions here
  • If dbg and PhpED are installed on the different networks and there is SSH tunneling setup between their machines please follow the instructions here
