Help & troubleshooting for channels on your Roku device, including adding/removing channels, logging in to, authenticating, or activating a channel, channel-specific playback issues, assistance contacting channel publishers to report issues, and adjusting channel-specific settings.
I'm having the same problem. I've been using Sling for 6 months and it's worked perfectly until yesterday (7-24-2020). Now the app won't load. I've contacted my ISP and they've been absolutely no help at all. I contacted Sling and they say its a problem with the ISP, which I believe is correct. When I use my Verizon mobile hotspot, Sling works again. When I switch back to my ISP, total failure. I've deleted the app and re-installed it and now get a message that streaming is not available in my area, which is ridiculous since I've been streaming for the past 6 months! Sling says this error (11-6) appears when the ISP sees an IP address from outside the United States. I am DEFINITELY inside the USA!
Bottom line, Sling blames the ISP and the experts at the ISP are clueless.
Sling is not the only pp that won't come up. All this happened after ROKU did there unannounced software update. Even trying to go to Settings and Update setting and all I get is that its trying to align the solar panels....really. Sling, Amazon prime, You tube- none will ome up....
It was "kinda" fixed. I'm in a rural area and have wireless internet service, which is rather slow by today's standards and not always reliable. My ISP told me they were having problems with one of their towers but said it had been fixed. One of their techs came to my house and aimed my antenna towards a newer, closer tower. That helped for a few days, but I still have problems. Sometimes Sling will load right away, sometimes it takes 5 or 6 attempts to get it to load. I'm contacting my ISP again, but I expect more finger-pointing.
I am having the same problem today. I have called Sling and they haven't been able to figure it out. I have shut Roku down and turned it back on several times. No luck. I have taken Sling off and put it back on. No luck.
Sling works on my laptop but not on the television. Very frustrating.
