Start by isolating the layer
Five things must all work: your details, your player, your device, your network, and the service. Two quick tests narrow it down more than anything else you can do.
- Try a different device. Enter the same details in a player on your phone using mobile data rather than Wi-Fi. If it works there, the service and your details are fine and the fault is your television or your network. If it fails there too, the problem is your details or the service.
- Try a different channel. If one fails and others play, nothing is broken — that is a single source, and no further troubleshooting will help.
Those two tests take two minutes and eliminate most of the possibilities.
Layer 1 — Your details
The most common cause of a total failure, and the easiest to dismiss because you are certain you typed it correctly.
- Check character by character. Long M3U URLs are copied incorrectly constantly.
- Look for a trailing space at the end of a pasted field.
- Check for autocapitalisation. Phone keyboards capitalise first letters; these fields are case sensitive.
- Do not change http to https or add a trailing slash to a server address.
- Check the expiry. If the subscription has reached its end date it will simply stop, because ours do not auto-renew.
Delete the playlist entirely and re-add it rather than editing the existing entry — some players cache a failed configuration.
Layer 2 — Your player
If the details are right, the app is next. An app that updated overnight is a classic cause of "it worked yesterday".
- Force-stop and reopen the player.
- Clear its cache in the device app settings — this fixes a surprising share of odd behaviour.
- Check for an update, and note whether one installed recently.
- Try a different player with the same details. If a second app works, you have found it.

Layer 3 — Your device
Televisions and streaming sticks accumulate problems that a restart genuinely clears.
- Power cycle properly. Unplug at the wall for thirty seconds — standby is not the same thing.
- Free storage and memory. Delete unused apps; force-stop background ones.
- Check the date and time. A wrong clock breaks secure connections and shifts the programme guide.
- Consider its age. A first-generation stick will struggle with 4K no matter what you do.
Layer 4 — Your network
If it works on mobile data but not at home, you are here.
- Restart the router and give it two minutes.
- Test the speed on the failing device, not on your phone by the router.
- Switch to Ethernet if at all possible.
- Turn off any VPN temporarily to rule it out.
- Check DNS. If the app cannot reach the server at all while other internet works normally, changing the device's DNS to a public resolver is worth a try.
Buffering specifically — rather than total failure — has its own dedicated guide.
Layer 5 — The service
If you have reached this point having confirmed the details are correct, a second player fails identically, the device restarts cleanly, and the connection is solid on Ethernet, then the fault is likely at our end.
That is the point to message us — and the troubleshooting you have already done makes it much faster to resolve. Tell us the device and player, what exactly happens, when it started, and what you have tried. We can then check from our side instead of asking you to repeat all of the above.
Quick reference
| Symptom | Likely cause | First action |
|---|---|---|
| Nothing loads at all | Details or expiry | Re-enter details from scratch |
| Worked yesterday, not today | App update or expiry | Check app update and end date |
| One channel fails | That source | Try the alternate listing, then report |
| Everything stutters | Network | Switch to Ethernet |
| Works on phone, not TV | TV network or device | Speed test on the TV |
| Guide empty | EPG still loading | Wait, then check EPG setting |
| Audio out of sync | Player buffer or TV processing | Restart stream; disable TV processing |
Start with what changed
Before working through the layers, spend thirty seconds on this question, because it frequently jumps straight to the answer.
Something that worked yesterday and does not today almost always has a cause in the last day or two. The usual candidates are an app that updated overnight, a television or streaming device that installed a system update, a new router or a router that was reset, an ISP change, or a subscription that quietly reached its end date.
- Did the player or the device update recently?
- Did anything change on the network — new router, new package, engineer visit?
- Did anyone else in the house change a setting or open a second stream?
- Is the subscription still within its term?
- Did you move the device, or plug it into a different port or input?
If one of these is a yes, start there rather than at Layer 1. The layered process below is for when nothing obvious changed.
Reading the error message
The wording on screen usually points at a layer directly, which saves working through the others.
An authorisation, login or subscription message points at Layer 1 or Layer 5 — your details or the service. A timeout or connection message points at Layer 4, the network. A format or codec message points at Layer 3, the device. And a message naming a specific channel, while everything else plays, is not a fault at your end at all.
Our guide on understanding IPTV error messages covers the common wordings and what each one means. If the channel has simply gone from the list rather than failing to play, when a channel disappears covers that instead.
When it fails on one television but not another
This is the most informative pattern there is, and it rules out half the possibilities immediately.
If the same login plays on a phone or a second television and fails on the first, the subscription, the credentials and the service are all working. The fault is that device, its app, or its connection — Layers 2 to 4, in that order.
Work through them in the cheapest order: clear the player’s cache, power cycle the device at the wall, then test its connection where it actually sits. Two platforms behave differently enough here to be worth their own pages: Samsung sets running Tizen and LG sets running webOS both have quirks that make the standard advice misfire. If a cable is available, trying it settles the network question in one step, as our comparison of Ethernet and Wi-Fi explains.
One caveat worth checking first: if your plan allows one stream at a time, a player left open on the working device can be the reason the other one fails. Our guide on how concurrent streams work covers it.
If you need to ask for help
When you have worked through the layers and it is still broken, the quality of what you send decides how quickly it gets resolved.
Have ready what you observed rather than what you concluded: the exact wording on screen, which devices and channels are affected and which are not, when it started, and what you have already tried. Our guide on what to check before contacting support sets out the full list, and working through it resolves a fair share of problems on its own.
If the app itself will not install or open rather than failing to play, that is a different path — when an IPTV app will not install covers it.
Frequently asked questions
Why has my IPTV stopped working suddenly?
The three most common reasons are that the subscription reached its end date, the player app updated overnight and changed behaviour, or the device or router needs a restart. Check the expiry date first, since plans do not renew automatically.
How do I know if the problem is my IPTV provider or my setup?
Enter the same details in a different player on a phone using mobile data rather than Wi-Fi. If it works there, your details and the service are fine and the fault is your television or home network. If it fails there too, the cause is your details or the service.
Do I need to restart my router for IPTV?
It is worth doing once if the router has been running for months, since it clears congestion and reassigns connections. It is not a routine requirement, and if you need to restart it constantly the underlying network problem is worth investigating.
Why does IPTV work on my phone but not my TV?
That points at the television specifically — usually its Wi-Fi reception, which is often much weaker than your phone's, or an app or memory problem on the set. Run a speed test on the television itself and try a wired connection.
It worked yesterday and not today. What changed?
Usually an app or system update installed overnight, a router change, or a subscription reaching its end date. Checking those five things first is faster than working through a full diagnostic.
What does the error message tell me?
A lot. Authorisation or subscription wording points at your details or the service; a timeout points at the network; a format or codec message points at the device; and a message on one channel while others play is not a fault at your end.
It works on my phone but not my TV. Where do I look?
The subscription and your details are fine, so the fault is the television, its app or its connection. Clear the player cache, power cycle at the wall, then test the connection where the television sits — and check no other device is holding your stream.
