1. Visit your account and see if everything is right with your M3U file.
2. Try to download it and open it with a text editor to see if it's populated.
3. Check the TVG-IDs and just to be sure, click the SAVE button, so your XML is generated again.
4. Download your XML file in your Browser and open it with a text editor to check if it's populated.
5. Check if you didn't try to connect with too many IP addresses.
If nothing's wrong on your account and with your file, go to our Status Reports Forum and see if we have something to say about your problem.
6. Check if everything is right with your media software/app. Contact their support!
7. Check if your media software/app has internet connection and if it's able to call the link.
If non of the above helped, contact us by Email, explaining the problem in detail!
That means: naming your hardware, naming your software, listing countries and channel names, telling us what you did and what you expected to happen, what happened instead etc.
