Hi,
I have read all the notes regarding this issue and I have the same issue. I purchased the Z11 ProMax in October 2024 and during the first month experienced the IPTV working fine but then stops working for hours. I tried upgrading my internet to the fastest available package as per my IPTV provider suggestion but it didn't help. Possibly too many users during peak times of the day, that is evenings and most of the weekend no IPTV. From about 11pm to 11am weekdays everything worked fine, but then during a show, usually around 6pm the screen went black and just the white circle appeared while it searched for internet signal and then displayed the message "please check internet connection....". After a few weeks of various experiments with boxes, cables, internet providers, tests, and frustration as I was very limited to only a few hours of available IPTV, my IPTV provider assisted me to set up a different portal from their 10 available packages, and from that moment on worked perfectly, 24/7 from November till almost March. For the last two weeks the same issue as before is occurring once again. Different from Skamerzz noted above, when I lose the live tv, I also lose VOD and TV series. Sometimes the tv show name will appear beside each channel but usually it reads no information when this occurs. I can try many things when this occurs, but the only fix is to turn off my tv and when I wake up in the morning or even during the night, everything is working perfectly.
I tried everything mentioned here as I would like to watch tv during the evenings, including using a different internet even though all other devices work perfectly, hotspot from phone, turning ipv6 on/off, executed DHCP, checked all router settings (no filters, timers, changed lease from one day to forever), tried private dns on Cloudfare, Quad9, Google, and back to automatic but no difference.
As everything works perfect outside of peak hours, this is the only thing I could come up with in my very limited knowledge of IPTV, that maybe too many subscribers accessing the Portal? Maybe since November they had many new subscribers to this Portal and it's bogged down?
Thank you.
