Sling Issue: Can't add as a source

I love this software. Very fast and intuitive. Like the TIVO I haven't used in 15 yrs. However, I integrated YouTube TV seemlessly with channels via their trial that ends tomorrow. I subsequently decided I could do the channels on Sling blue. Unfortunately, I keep getting an error with sling when I try to add it on my server " Cable provider authentication failed" is the notice - despite my confirming my account on Sling and logging in on their site. Anyone know of any known issues?

I’m not a sling user so can’t confirm but I would recommend submitting diagnostics from the DVR web UI. The Devs can look and hopefully see what’s happening.
