I installed a new Xfinity gateway, and now I cannot access Sling from my laptop, phone, or AppleTV. I do not have this issue when switching back to the old modem.

On the laptop browser, I get the following error:

Hello @user_4l5iwd, Thank you for reaching out on our Community Forum. It looks like Sling is being blocked for some reason. I would like to dig into this further for you.

Please send us a direct message with your full name and address so that we can assist you further.

To send a "Direct Message" to Xfinity Support:

Click "Sign In" if necessary

Click the "Direct Messaging" icon or  https://forums.xfinity.com/direct-messaging

Click the "New message" (pencil and paper) icon

The "To:" line prompts you to "Type the name of a person". Instead, type "Xfinity Support" there

- As you are typing a drop-down list appears. Select "Xfinity Support" from that list

- An "Xfinity Support" graphic replaces the "To:" line

Type your message in the text area near the bottom of the window

Press Enter to send it.
