How to fix the issue of dynamic DNS not updating in OpenWRT?

If your OpenWRT dynamic DNS settings are not updating, you can try the following troubleshooting steps:

1. Check the dynamic DNS settings: make sure that the information you input for the dynamic DNS service provider (such as account, password, hostname, etc.) is correct.
2. Check your network connection: make sure your router is properly connected to the internet. You can try restarting the router or checking your network settings.
3. Check the firewall settings: Sometimes firewall settings may prevent dynamic DNS updates. Make sure your firewall is not blocking the traffic for dynamic DNS updates.
4. Check if the dynamic DNS service provider is functioning properly: Sometimes, the dynamic DNS service provider may experience issues or maintenance which could result in update failures. You can contact the dynamic DNS service provider to confirm if there are any problems.
5. Updating your OpenWRT firmware: If the above methods don’t work, you can try updating your OpenWRT firmware to the latest version, which may fix some issues caused by bugs.

If the methods above are not effective, we suggest contacting technical support from the OpenWRT community or your dynamic DNS service provider for assistance.
