# How to change default OpsHubTFSService port number?

### Description

By default OpsHubTFSService is registered on port number `9090`. If `9090` port is used by any other application/process, then you can change the port number.

### Solution

To change default OpsHubTFSService port number you need to perform the following steps:

* Open file `<code class="expression">space.vars.SITENAME</code>_INSTALLATION_PATH>\Other_Resources\Resources\OpsHubTFSService\opshubtfsservice.exe.config`.
* Find the line `<add baseAddress="http://localhost:9090/TFSService"/>` and instead of `9090` change port number with which you are going to register.\
  e.g. If you want to register with `9191` then change the line as `<add baseAddress="http://localhost:9191/TFSService"/>`.
* If you have not registered the OpsHubTFSService then refer [this](https://docs.opshub.com/v7.216/help-center-index/faqs/tfs-faqs/register-opshubtfsservice) for registering OpsHubTFSService.\
