The port 443 in the service conflicts with the device managed port 443.

Hey, @fredtrem22. We'd be glad to help with your port 443 conflict. Before we can assist you further, we'd like to know a little more about the situation.

• Do you have AT&T internet service? If so, what internet plan do you have?
  
  
• If you do have our service, are you only experiencing this on our network? Have you tried connecting to non-AT&T networks?
  
  
• Are you only having trouble with a single device, or every device?

We look forward to your response!

Ramses, AT&T Community Specialist
