I'm looking for a way to contact Sling TV for support. I operate a small WISP and have recently rolled out a new ARIN IPv4 allocation to my customers. After switching one customer's IP address, they are getting an HTTP 403 error when trying to access Sling.com, regardless of the browser used. I added this new IP to several Geo IP databases and have set up reverse DNS as well. My customer, who is older, has difficulty finding a phone number for Sling to report the issue, and unfortunately doesn't have a smartphone to use the Sling app. I've also reached out on the NANOG mailing list but haven't received a contact. It seems like there might be a WAF in place or some filtering that incorrectly blocks the new IP. Any advice would be appreciated!

It sounds like your new IP range might be too fresh, which could result in it being stuck on Sling's blocklist. Have you tried using a VPN to see if it bypasses the restriction? That could help your customer access the site for the time being.
If I were you, I'd post this in a networking community for more targeted advice. There are people there who might have dealt with similar issues. You could also consider reaching out to tech support channels directly related to Sling, even if it means using their online help forms.
A quick fix someone suggested is to run "sfc /scannow" and reinstalling Windows, but I doubt that'll help with IP issues. Have you confirmed that everything is good on your end with the connection?
Your new IPs may already be blacklisted by Sling or their ISP. Unfortunately, many companies have outdated filters that could be blocking access. It might take some time to resolve, but I'm not sure calling Sling would help either. Maybe check their help or support forum online.
