# Could not startup server, Contact Apps For Tableau support when the problem persists

The app server is unable to start. This can have multiple causes, such as:

* The application is configured as administrator but is currently not running with administrator privileges.
* Another WriteBackExtreme process might be running in the background. Open Task manager and select the `Details` tab. You should have only one process called WriteBackExtreme.
* Other processes might be running on the port that is configured in WriteBackExtreme. You can do that with this command in cmd:

<a class="button secondary">Copy</a>

```
netstat -aon
```

* Open Powershell and navigate to the directory where WriteBackExtreme.exe is located. run this command to manually trigger the application server:

<a class="button secondary">Copy</a>

```
./WriteBackExtreme.exe serve
```

This command might give more details about what went wrong.

* Check the error logging in `./wbe-runtime/storage/logs/` This will probably show the underlying reason. We have [a page of common error messages](https://docs.infotopics.com/writebackextreme/support/troubleshooting/errors) you might see that will help you solve the problems.
