Xfinity/Rogers Advanced WiFi Security Blocks NextDNS

Hello NextDNS,

I encountered an issue today of my local ISP Rogers blocking next DNS and misclassifying it as a malicious service. Rogers uses modems and network services provided by Xfinity from the USA and it seems like this issue may also be present on their CPE(customer premises equipment) as well. I am reaching out to them to resolve this issue but wanted to share if others were having the same issue. This only impacted my IPv4 DoH traffic, unencrypted DNS v4 and encrypted v6 worked with no issues.

ISP: Rogers Cable
CPE: XB7
