Issues With Iptv Add-ons

I use Kodi 17 on a new Nvidia Shield TV box. I have been adding a lot of add-on’s with no issue. Those that run movies and sports per-se. But every IPTV type add-on I get installed, I get a error log message. I have read the log and it reads “Control 50 in window 10025.” I have loaded several IPTV type add-ons, including MiamiList, Stallion and Falcon, which I believe are all IPTV type add-on’s. I only get these errors with these type of add-ons. Does anyone have the same issues or have repaired the errors somehow. I spent hours in the last few days with Google searches to find the solution. But I can’t find a solid answer.

Can anyone help? This is my first question here on this forum.
