The “Unable to Obtain IP Address” error is one of the most common issues users face when connecting with WatchGuard Mobile VPN on mobile devices. This problem prevents the VPN client from receiving a valid IP address from the corporate network, making remote access impossible. Fortunately, most cases can be resolved quickly with the right troubleshooting steps.
This guide provides clear, step-by-step solutions specifically for iOS and Android users.
Why the “Unable to Obtain IP Address” Error Occurs

- Conflicts with mobile OS settings or other VPN profiles
The good news is that the majority of these issues can be fixed without advanced technical knowledge.
