The channel is showing the wrong programme." The stream is fine. The picture is correct. The guide is wrong. This complaint means your EPG is the problem. Not your source.
In my second year as a British IPTV reseller, I wasted hours on these complaints. I checked sources. I reset streams. The problem was always the EPG. The guide data was wrong.
Here's the thing. Your IPTV reseller panel provides EPG data from a separate source than the video stream. The video can be perfect. The guide can be wrong. They're independent.
Most IPTV reseller operators don't understand this. They treat all complaints as source issues. They waste time.
What actually works is a standard EPG response. "The programme guide is sometimes wrong. The actual channel content is correct. I'll refresh your EPG data. It should update within 24 hours. For now, ignore the guide and watch the channel."
A smart British IPTV reseller I knows has an EPG refresh button in his panel. He clicks it. He tells customers to refresh their app. Most EPG issues resolve within an hour.
Here's a real-world example. Customer complains about wrong guide. Reseller A spends an hour troubleshooting source. Reseller B clicks EPG refresh. Tells customer to restart app. Fixed. Same IPTV panel . Different diagnosis.
The pattern is that EPG issues are common and usually easy to fix. Don't overcomplicate them.
What to do when EPG is wrong. Refresh EPG in your panel. Tell customer to clear app cache. Tell customer to restart app. Wait 24 hours for data to repopulate.
If EPG is consistently wrong for specific channels, consider switching EPG providers. Some panels allow multiple EPG sources.
I've learned to ask one question. "Is the actual channel content wrong, or just the guide?" If the content is right, it's EPG. If the content is wrong, it's source.
EPG issues are annoying. They're not emergencies. Handle them efficiently. Move on.
The guide is not the destination. The channel is.
