E-DTT-1: No Internet
What this error means
Your Trainer successfully connected to your Wi-Fi network but cannot reach the remote server. This typically indicates that your router or firewall is blocking the device from accessing the internet.
Info
The device has network connectivity but external communication is being restricted by your network configuration.
Common causes
- Strict firewall settings — Your router's firewall security level is too restrictive
- Device blocking — The Trainer is blocked in your router's Access Control or Security settings
- Network filters — Features like child protection, IoT isolation, or private network modes are preventing outbound communication
How to fix this error
Step 1: Access your router settings
Open a web browser and navigate to your router's admin panel. Most routers use one of these addresses:
192.168.0.1192.168.1.1
Tip
Check the label on your router for the correct address and default login credentials. You can also search online for your specific router model's setup instructions.
Step 2: Check for blocked devices
Look for settings menus labeled:
- Access Control
- MAC Filtering
- Device List
- Connected Devices
Verify that your Trainer device is not on a blocked or restricted list. If you find it blocked, remove it from the list and save your changes.
Step 3: Adjust firewall settings
If your router offers firewall security levels (High, Medium, Low):
- Change from High to Medium or Low
- Save your changes
Warning
Only lower your firewall settings if you understand the security implications. Medium is usually sufficient for most home networks.
Step 4: Reboot your devices
Restart both devices in this order:
- Power cycle your router (wait 30 seconds before turning it back on)
- Restart your Trainer device
Wait 2-3 minutes for everything to reconnect, then check if the error clears.
Alternative: Test with a mobile hotspot
If the error persists after adjusting router settings, your router may have IoT traffic filtering that cannot be easily disabled. Use your phone's hotspot to confirm this is the issue.
Step 5: Enable your phone's hotspot
Turn on the mobile hotspot feature:
- Android: Settings → Network & Internet → Hotspot & tethering
- iPhone: Personal Hotspot Guide
Step 6: Connect the Trainer to your hotspot
- On your Trainer, open the Wi-Fi setup page
- Using a laptop or second device, connect to the "Trainer Setup" Wi-Fi network
- Follow the setup steps to connect the Trainer to your phone's hotspot
Step 7: Verify the connection
If the error disappears when connected to your phone's hotspot, this confirms your home router is blocking the device.
Success
Success! The Trainer can reach the internet through your mobile connection.
Permanent router configuration
Once you've confirmed the router is the issue, you can create a permanent fix:
Create an allow rule for the Trainer
Add the Trainer's MAC address to your router's allowlist or whitelist. This ensures the device always has internet access regardless of other security settings.
Find the MAC address in your Trainer's network settings or on the device label.
Adjust IoT device settings
Some routers have specific IoT device settings. Look for options like:
- IoT Network — Add the Trainer to a trusted IoT network
- Device Priority — Set the Trainer to high priority
- Access Scheduling — Ensure no time-based restrictions apply
Summary
Note
Error E-DTT-1 indicates your device has local network access but cannot reach the internet due to router or firewall restrictions.
Follow the steps above to allow traffic through your router's firewall, or use the mobile hotspot test to confirm the issue. Once outbound traffic is permitted, the Trainer automatically reconnects and the error clears.
