# How to change Agent Port

You may wish to change the port that Leapwork Agent listens on from the default one (6777) to a different value if another application is already running on the default one as that will cause the Agent service to fail during startup.

**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 Agent:**  
   - Press Win+R combination to open the Run dialog.
   - Type ‘services.msc’ and press Enter to open Services window.
   - Find Leapwork Agent service and stop it using the right mouse button click and “Stop” command.

2. **Change Leapwork Agent port:**  
   - Navigate to C:\Program Files\Leapwork\Agent.
   - Find the "agent.config" file and open it as administrator using Notepad.
   - Change “AgentPort” to some other port (shown below) save and close the config file.

3. **Start Leapwork Agent service.** Just follow the steps from point number 1, but use the “Start” command at the last step.

Port is now changed, make sure you open TCP Port{new Agent port} in your firewall before testing connection.

Once firewall port is open test agent connection using Leapwork Studio as shown below.
