H b o max is no longer showing up on my xfinity channels

I have not changed my plan in quite some time. When I go to HBO Max, it wants me to sign in it. Then, ask me, if I have a provider, and I put the provider in as xfinity, and then it gives me a code, and I put the code in and nothing happens. Up to this point I had HBO Max.

Good evening user_xu52yv. You have reached the right team. I will be more than happy to assist you further. I do have a few questions to get a better understanding. Are you having trouble accessing HBO Max directly through an Xfinity box? Or are you having trouble accessing it on another device? If it is an Xfinity box, and you haven't already, can you try clearing the locally stored data? Here is the information on how to do that. Also, have you unplugged the box for 30-seconds, and plugged it back in yet?
