Using v18
Getting an error when selecting a channel group.

 You haven't turned on the Kodi Web Server service. https://kodi.wiki/view/Webserver

Code:

Error Contents: HTTPConnectionPool(host='localhost', port=8080): Max retries exceeded with url: /jsonrpc?request=%7B%22jsonrpc%22%3A%222.0%22%2C%22method%22%3A%22PVR.GetChannelGroups%22%2C%22id%22%3A1%2C%22params%22%3A%7B%22channeltype%22%3A%22tv%22%7D%7D

Quick Start

• Turn on the Web Server in Kodi and enable Remote Control. (this addon uses jsonrpc)
  

 

Funny thing is that it was turned on... I didn't change anything on my PC and it worked this morning. Go figure. I have had several json issues with v18.   

 
8080 is a commonly used port so I wouldn't be surprised if another program on your PC was already using it.
Even Skype steals port 80 and port 445 if you don't turn it off, or at least it used to.

This is useful to see ports being used. https://www.nirsoft.net/utils/cports.html
