# If All Ports Are Unavailable

If you see an error indicating that all ports are unavailable, it usually means another application or service on your device is currently using the same port range that 9Proxy is trying to allocate.

## 1. Possible Cause

Some software, browsers, or background services may be occupying the same ports or blocking access to them.

Common causes include:

* Other proxy or VPN applications running in the background
* Web browsers with proxy extensions using the same port range
* System services or security software that reserve ports

## 2. Solution

Try one of the following solutions:

### 2.1. Option 1: Close Conflicting Applications

* Close any other proxy tools, VPN software, or browsers that may be running.
* Make sure no background process is using the same port range as 9Proxy.
* Once closed, try opening the 9Proxy app again.

### 2.2. Change the Port Range

Open the 9Proxy app and assign a different port range that isn’t already in use. For detailed steps, see How to Change the Port Range.

### 2.3. Option 3: Restart Your Computer

If the issue persists, restart your computer to release any ports locked by background services. After restarting, open the 9Proxy app and check the port status again.

## 3. Still Not Working?
