I have the same issue.  Using my iPhone to try to log into the app and can’t even get to the place where I can enter my password. Called the Xfinity customer service number and after an hour on the phone, they said they would “transfer me to the expert to fix the problem,” and then they hung up on me.  

Sorry to hear about your experience @user_gr22xr. I wouldn't want to wait on hold for so long just to get hung up on, we definitely dropped the ball.

In regard to the Xfinity Stream App, do you have the most up-to-date version installed? Are there any software updates needed on your mobile device?

@Xangz I would be more than happy to help figure out a solution to this restricted access issue you're experiencing. So that we don't go over something you've already done, can you please share with me what troubleshooting steps have you completed on your own?

I get the same "access denied" after I successfully login and provide the security code. This happens on my windows 11 computer but I can successfully login on my son's windows 10 computer with no issues. We both use bitdefender safepay and are in the same house. I've been a customer since 1993 and it really bothers me that I can't freely pay my bill using my computer. My son encouraged me to seek out a solution instead of relying on his computer, which I was trying to do anyway. Surely you can help me solve this issue. Frankly, I don't know what to do but I'm sure someone on your tech team can help or else what good is your service. Why is it saying:

Access Denied

You don't have permission to access "http://login.xfinity.com/login" on this server.

This is the full message that appeared on my attempt after providing the security code sent to my phone from xfinity. Please don't tell me to try the xfinity phone app instead. I want to be able to use my computer only to pay my bills and I should be able to. Thank you for your quick response. I'm sure you will agree that Xfinity does 

need to solve this problem for the sake of many unhappy customers.
