By family firewall profile, do you mean parental control profile?

Yes, correct.

If you disable the parental control, will IPTV services start working again? If so, please let us know the detailed setings of your parental control profile.

If all Parental control profiles deleted then yes IPTV will back to work.

By the way, was the settings the same before updating the firmware and IPTV sevices was working fine before?

Yes, it was there before updating, but anyway I have reset the router and IPTV works fine but after creating a parental control profile then IPTV will stop on all devices connecting to my network.

Please find attached the screenshots of the family parental profile.

ISP is Etisalat/UAE but I checked with them and there is nothing blocked by them.

Once I create any family parental profile with even basic settings and no filtering at all , then IPTV stops on the TV and be informed that the TV is not part of any parental profile.

I tried the beta software and it is the the issue.

  @Fakhrkh Hi, not meaning to hijack this thread, but I also have an IPTV issue with the 1.2.6 firmware. In Australia, Samsung TV, the Samsung TV Plus feature stopped working after upgrading from 1.2.3 to 1.2.6 firmware. I also have a HomeShield profile on the router. I tried the beta firmware suggested, but IPTV still did not work. I have currently downgraded to 1.2.3 firmware to get IPTV working again.
