Mixed Content: HTTPS and HTTP
Mixed Content: The page at 'https://iptvnator.vercel.app/portals/...' was loaded over HTTPS, but requested an insecure XMLHttpRequest endpoint 'http://ip.tv'. This request has been blocked; the content must be served over HTTPS.
Besides that I can't seem to make it, let it play the video in the browser. In the url it has &extension=ts, but the only one that kept loading forever and gave me this issue was the HTML5 player, but still with no success
Besides that it is cached, so after a few seconds it will close the player and stop the video. How would I fix this?
That's a browser restriction. Most modern browsers will block http assets if the main site is accessed over https due to security concerns.
Many iptv providers use http links for their streams because https uses encryption, which creates additional overhead (cpu utilization).
If your provider does that, you'll have to access the iptvnator interface over http.
