Definitely getting a 403. Can you toggle "Enable Debugging [Log Errors]" via Sling add-on settings and try playing something, via guide is sufficient or whichever is easiest. Then provide me that log. I tried two separate devices, even the same channel "Food Network" all with no issues.  

I did have debugging on on the last log and tried several channels. Now getting log file too large to upload.   

Here is the log....https://paste.kodi.tv/abehahucoc  

I'm sorry but Sling debugging is turned off in that log. I need it to see what the add-on is submitting for licensing. The screenshot below shows it toggled "ON"
