Can't access some websites
It's happening again!
I see other people with this problem so I know I am not alone here.
Using different computers and different browsers all give the same error message no help.
Restart modem, check IP, it's not blacklisted, all computers malware checked.
Everything worked fine yesterday get up this morning and can't access these websites.
Switch to T-mobile Hotspot and connect computer and everything is fine.
Maybe I should switch to their internet service. Please help

The problem seems to have gone away a little bit at a time. I still have the same IP address and it still seems to be blacklisted but
every day or so last week I was able to get back on a couple of the problem websites daily. First it was Citizens bank and Fidelity, then
Guitar center and American Airlines, Costco, DSW, etc until I am now able to access them all. I don't know how or why just glad it's working again.
Thanks for all the help and suggestions.

Check to make sure that your proxy settings are correct.

All three of these sites are located on Akamai's network. See https://community.akamai.com/customers/s/article/Why-is-Akamai-blocking-me?language=en_US (thanks to @Hemingray42 for finding that page).
"Access Denied / You don't have permission" messages are issued by the destination site, not by Comcast. It's likely the sites are blocking your public Comcast IP. You can look up your IP at https://www.google.com/search?q=my+IP.
It would be a good idea to scan your systems for malware. A person or a program using your Internet service is doing something these Akamai customers don't like.
You'll probably need to ask the sites' admins for help with this.

The reason why you have access problem on certain website is because your public IP address has been blacklisted in some anti-spam database.
You can confirm that your public IP address has been blacklisted from to this site but you will need to know your public IP address (see next paragraph to find your public IP address)
https://whatismyipaddress.com/blacklist-check
Your public IP address is assigned by your internet service provider, which is Xfinity in this case. You can find your public IP address in your router setting. Or you can find your public IP address from https://www.google.com/search?q=my+IP
If you click on one of the blacklisted sites from the above website, you'll find out why you have been blacklisted.
In my case, my public IP address was blacklisted for not having rDNS which stands for reverse DNS.
This reverse DNS should be assigned by the internet service provider, which in this case is Xfinity.
I called Xfinity and all they told me was to change my modem to Xfinity's. If I change my modem it would work since I would get a new public IP address.
Also if you wait long enough, this problem resolves by itself because Xfinity will periodically change your public IP address. This is the reason why it seemingly seems to repair by itself if you wait long enough. But I could not get an answer from Xfinity exactly when my public IP address would change.
You can also change your router and you will also end up with a new public IP address.
I've had this recurring problem a few years ago and I just had it again last week. Since I cannot get help from Xfinity, I just end up swapping routers back and forth every time I have this problem.
Yes, Xfinity should solve this problem but they won't. Maybe they're trying to sell modem so they can make more money.
If your public IP address has not been blacklisted for not having reverse DNS, you may have a bigger problem.

They won't do it. If you have a rental gateway you'd have to:
If you are already using your own modem and router or you've added a router to a rental gateway in bridge mode, just use the router's "clone MAC" facility, and then reboot the modem.
A VPN is another possibility. If you use one your public IP won't actually change, but systems you connect to will see the IP provided by the VPN rather than your actual public IP.
