How can I access my Management Console of a Cloud Installation, when I have been Blacklisted?

The Problem

If your 3CX is installed on a Hosting Provider, you may accidentally get locked out of the Management Console. This could happen for a number of reasons, like blacklisting the wrong IP ranges, enabling Console Restrictions for the wrong IP, etc.
Let's take a look at how to solve this and get you back into your management console as soon as possible.

What do I need to solve this problem?

  • Access to the Operating System:
    - If it's Linux, SSH access to the machine (Secure Shell)
    - If It's Windows, RDP access to the machine (Remote Desktop)
  • The Username and Password of your Management Console

How do I access to the Management Console?

Linux

  1. Download PuTTY from here: https://www.putty.org/
  2. Enter all the information required to connect to your machine over SSH like Host Name, Port, Private Key, etc, but do not start the connection attempt yet.
            Note: the settings on how to connect to your instance are not covered by this guide
  3. In the PuTTY settings, go to Connection → SSH → Tunnels


  4. Add a new Forwarded Port, where Source: 45000 (or any unused port) and destination: 127.0.0.1:5000, then press "Add".


  5. Open the SSH connection and log in if required.
  6. Open your browser on the PC you connected from and navigate to http://127.0.0.1:45000
  7. The 3CX Management Console should appear and you can use your Username/Password to login
            Note: if the Management Console does not appear, try repeating these steps, but in step #4 choose a different source port

Windows

  1. Connect to the Windows machine using Remote Desktop
  2. On the Remote Desktop, open a browser and navigate to http://127.0.0.1:5000
  3. Login using your Username and Password
