Authentication Errors

Symptoms: "Invalid credentials", "Login failed", "Authentication error", "Cannot connect to server"

Diagnostic steps:

  1. Verify credentials in your panel — confirm username, password, and server URL are exactly as shown
  2. Ask client to re-enter credentials manually (not copy-paste — copy-paste sometimes introduces invisible spaces)
  3. Confirm server URL includes "http://" or "https://" prefix
  4. Confirm client is entering credentials in the correct fields (server URL is not the username)
  5. Test credentials yourself in IPTV Smarters Pro — if they work for you, the issue is client-side entry error
  6. Check if the subscription has expired in your panel

Most common resolution: Credential entry error (spaces, wrong capitalisation). Resolution: resend credentials and ask client to enter one character at a time rather than copying.

Buffering and Freezing

Symptoms: Stream freezes, loading spinner appears, stream stops and starts

Diagnostic steps (follow in order):

  1. Check if other clients are affected — if yes, server-side issue; contact supplier
  2. Run Speedtest.net on the IPTV device (not phone/computer) — confirm 15+ Mbps download
  3. Ask: Wi-Fi or Ethernet? Request they try Ethernet if on Wi-Fi
  4. Try a different channel — if one specific channel buffers but others do not, report that channel to supplier
  5. Clear IPTV app cache and restart app
  6. Restart router and device
  7. If still persisting, report to supplier with specifics

Missing Channels

Symptoms: Client cannot find specific channels; channels they expect are not visible

Resolution steps:

  • Ask which specific channel they are looking for — they may be searching wrong name
  • Force a playlist refresh in the app (Settings → Refresh Playlist)
  • Check channel is in the correct category (Sky Sports channels in Sports; UK channels in UK section)
  • Search for the channel by name using the in-app search function
  • If a specific channel is definitely missing, report to your supplier

App Crashes

Symptoms: IPTV app closes unexpectedly, freezes on loading screen, becomes unresponsive

Resolution steps:

  1. Device Settings → Apps → select IPTV app → Clear Cache and Clear Data
  2. Restart device completely (power off, wait 30 seconds, power on)
  3. Update the IPTV app to latest version
  4. Check available storage — IPTV apps need 500 MB+ free storage to operate
  5. If app continues to crash: uninstall, reinstall, and reconfigure

EPG Issues

Symptoms: No programme guide showing, wrong shows displayed, EPG showing yesterday's schedule

Resolution:

  • Force EPG refresh in app settings
  • Allow up to 30 minutes for full EPG load on first setup
  • Check EPG time offset setting — adjust to GMT or BST as appropriate
  • If no EPG at all: confirm XMLTV URL is configured correctly in app settings

When to Escalate to Your Supplier

Escalate to IPTVReseller.store support (Standard: +44 7311 128276 / Premium: +44 7415 056075) when:

  • Multiple clients report the same issue simultaneously — server-side problem
  • A specific channel is consistently unavailable across multiple devices
  • Authentication fails despite correct credentials verified in the panel
  • A client's subscription shows active in panel but credentials are rejected by the app
  • Unexplained credit balance discrepancies in your panel

Always provide: your reseller username, the client's username, the device type, the IPTV app used, the specific issue and error message, and whether other clients are affected. This information enables fast supplier diagnosis.

Frequently Asked Questions

Run the speed test remotely with them — ask them to install Speedtest on their Firestick, run it, and send you a screenshot. If the speed is below 15 Mbps, you have objective evidence. Say: 'Looking at your speed test, you are getting [X] Mbps at the device — for HD IPTV we need at least 15 Mbps. Your internet connection is causing the buffering. Contact your ISP or try an Ethernet connection.'
Most common issues (credential errors, buffering from Wi-Fi) should be diagnosed and resolved within 10 minutes of initial contact using the diagnostic frameworks above. App crashes take 15–20 minutes including clear-cache and reinstall if needed. Device-specific issues occasionally take longer if firmware or account issues are involved.
No — extensions are goodwill gestures for genuine service failures, not for client-side configuration issues. Offering extensions for every complaint trains clients to complain for discounts. Reserve extensions for: confirmed server-side outages affecting streaming for 30+ minutes, genuine supplier failures that directly impacted client viewing.
Client username and panel expiry date, device type and IPTV app version, exact error message (screenshot preferred), time the issue started, whether it affects one channel or all channels, and whether other clients are affected. The more specific the report, the faster the supplier resolution.
