NAT Hosted Application Issues

Hello @prodrigue, thanks for notifying us about your concern!

Let’s make up for the invested time and find out what's causing this.

For this issue we recommend you factory reset your router, so please follow the troubleshooting steps:

Before doing a factory reset, which will delete custom settings, try to reboot your Wi-Fi gateway.

Reset gateway!

Heads up: Be sure to jot down your custom settings, like your static IP address if you have one, or your Wi-Fi® network name (SSID). You can then change them back after the factory reset.

1. Press and hold the gateway Reset button for at least 10 seconds. If you let go before 10 seconds, the gateway will reboot, but it won’t reset.
2. Wait until the gateway restarts and all the status lights are lit. 
3. See if the Broadband or Service status lights are solid green. If so, the reset worked.

   We hope this helps!
