First, confirm the device is online
Open a website or another streaming app on the same device. If nothing loads, the device really is offline: restart the router and the device, and see IPTV not working on Wi-Fi. If everything else works, carry on below.
Fixes, in order
1. Set the clock to automatic
Secure connections check certificates that are only valid between set dates, so a device whose clock is far out fails them. In the device’s settings, turn on automatic date and time and the right time zone. Google’s Android help also suggests turning automatic date and time off and on again when an app isn’t working. Devices that have been unplugged for a long time are the usual victims.
2. Sign in to the Wi-Fi, if it asks
Hotel, student, café and some workplace networks show a sign-in page before they let you online. A TV app can’t display that page, so it just reports no connection. Open a browser on the same device, or sign in from a phone if the network allows several devices. A server reply of error 511 means exactly this; see IPTV error codes.
3. Check DNS settings
DNS turns the server’s name into an address. If it fails, the app can’t find the server and may call that “no internet”.
- On Android phones and tablets, open SettingsNetwork & internetPrivate DNS. Google says the default uses Private DNS with any network that supports it. If someone has set a provider hostname that’s mistyped or no longer works, names stop resolving: set it back to Automatic.
- On the router or device, a custom DNS server that has stopped working has the same effect. See DNS for IPTV.
4. Turn off VPNs and proxies
A VPN that has disconnected, or one the IPTV server refuses, stops the app reaching it. Turn the VPN off, restart the app and test. See VPN and IPTV.
5. Check broadband filters
Broadband security and parental filters can block a server they consider risky, for every device in the home. Test the app on mobile data; if it works there, see IPTV not working on Wi-Fi for the filters UK providers use and how to check them.
6. Clear the app’s cache
A corrupted cache can leave an app stuck on an old error. Force stop the app and clear its cache; see IPTV app keeps crashing for where those options are.
If none of that helps
The server itself may be down or refusing your connection. Test the same login on another device and on mobile data. If it fails everywhere, see server unavailable or not responding.
