Troubleshooting

Overview

A number of issues may prevent Port Forwarder from working as expected.

Battery optimizations

More recent versions of Android have introduced battery optimizations.

IP Address

When you switch from one network to another your device's IP Address changes, namely:

1. Mobile data
2. Wi-Fi
3. When connected to a VPN

Check that you are using your current IP Address when configuring Port Forwarder.

Secondary device cannot connect to primary device

A few possible causes may result in this behavior:

1. The primary device is connected to a mobile network and the secondary device is not sharing the connection via a Hotspot. Network operators block all incoming connections to your mobile device when connected to the mobile network. There is unfortunately nothing that can be done in the Port Forwarder application to work around this.
2. The two devices are on different networks i.e. Primary device on Network A and secondary device on Network B. Both devices need to be on the same network for connectivity to be established.

Notifications

Enabling notifications can help to diagnose connectivity issues.
