Error Configurating pvr iptv simple client

Hi everyone!:

When i’m trying to configurate my iptv client on kodi krypton it appears this when I click on the TV button. It also doesn’t show me the confirmation sign when I finish to configure the iptv client, it’s just puts on “enabled” mode

Does anyone have an idea to solve this? I’ve tried with 5 different lists, turning off and on Kodi, and so on
