So I had no luck using the stalker Client with the updated Stalker EPG updater. I had deselected "Configure" PVR Stalker" so it didn't mess up the serial and device ID's but I still get the authorization error. I am Portal 1 so the server address should be portal1.iptvprivateserver.tv/stalker_portal/c/index.html right? Only asking because I see varying suggestions in the posts. And scope should I still use remote URL and I had previously used the number 1. I switched to the local URL but no luck. Also then I started using the PVR Simple Client and I followed instructions and it works although what's weird is it loads in the channels in my firestick but no when I click on a channel it shows "working" for a few seconds but doesn't load the channel. On my firetv, there's no problems.
