Desktop says that device is paused even though it is unpaused in the app

My desktop gets notifications that the device is paused but I cannot connect to the internet. The Xfinity app says that the device is unpaused. I have tried to restart my modem and my computer several times but the internet still will not connect. I have no trouble connecting to the internet on other devices. I tried to call customer service but gave up after being on hold for over one hour.
