My ISP is Xfinity and I am using an SBG10. This has been driving me up a wall for months. My Windows11 laptop cannot reach Apple’s servers to authenticate to iCloud unless I turn off the SBG10 Firewall. This is independent of whether I use Chrome, Edge, DuckDuckGo, or Apple’s iCloud app. (Disabling Windows Defender and firewall also had no effect.)
I CAN however connect the laptop to my phone’s hotspot (also Xfinity) and get to iCloud. I can also use my old Windows 10 computer from my SBG10 Wi-Fi to get to iCloud. (Not a good workaround anymore since that machine is on it’s last legs and needs to be retired.)
Is there some secret incantation I need to learn if I want to keep the SBG10 firewall on?
