How to change the port number of the LEAPWORK Controller after installation

Uninstall and Re-Install

During the installation it is possible to specify the port number. Be aware that all work done will be removed using this approach.

To un-install LEAPWORK do the following:

1. Open a run box by pressing “LEFT WINDOWS” key and “R”: 
2. Enter “control panel” and press “ENTER”
3. Select “Programs – Uninstall a program” and find LEAPWORK in the list of installed programs.
4. Right-click LEAPWORK and select Uninstall.

To re-install please follow the article: Download and/or Upgrade LEAPWORK.

Changing the port settings manually

The (very) manual way of changing the port number and avoiding a re-installation is described in the following:

1. Stop the LEAPWORK Controller:
   1. Press Win+R combination to open Run dialog
   2. Type ‘services.msc’ and press Enter to open Services window
   3. Find LEAPWORK Controller and stop it using right mouse button click and “Stop” command.
2. Change LEAPWORK Contoller port:
   1. Navigate to C:\Program Files\LEAPWORK\Controller
   2. Find controller.config file and open it using Notepad
   3. Change “ControllerPort” to some other port
3. Update the LEAPWORK controller port in Studio:
   1. Open LEAPWORK, Navigate to Settings=> Controller settings
   2. Create new controller or Edit the existing one 
   3. Update the new Port number (changed in point number 2 above) and save.
4. You need to open the selected port at the system firewall. Note that LEAPWORK installer does that automatically during installation,
   1. On the Start menu, click Control Panel
   2. In Control Panel, find and then open Windows Firewall
   3. In Windows Firewall, click the Advanced settings menu
   4. Press right mouse button at Inbound Rules and then click New Rule
   5. Select Port and press Next
   6. Select TCP rule at the next step and type Specific port
   7. Select “Allow the connection” and apply rule to “Domain”, “Private” and “Public”
   8. In the Name box type LEAPWORK Controller and press Finish
   9. Repeat the same steps for Outbound Rules.
5. Start LEAPWORK Controller. Just follow the steps from point number 1, but use “Start” command at the last step.
6. Open LEAPWORK Studio and check if it can connect to the configured Controller. You can always see the address that LEAPWORK Studio is trying to connect to the LEAPWORK Controller with, at the left bottom corner of application.
