Can't sign into AT&T account or even access the website as of 2 days ago! I only have the Edge Browser. When I click on my user name, I get an error message that says something went wrong!I can't even access customer support for AT&T! I get the following message:

Access Denied

You don't have permission to access "http://www.att.com/support/article/my-account/KM1009058?" on this server.

What is happening and how do I fix this error?

Hi! This can happen suddenly if your IP address, cookies, or browser headers were recently blacklisted, or if you’re using a VPN, proxy, or even certain browser extensions. Since you mentioned this started just two days ago, it’s likely tied to either cached browsing data or an IP reputation issue rather than a permanent block.

To fix this, start by disabling any VPN/proxy, then clear Edge’s cache and cookies (edge://settings/clearBrowserData) and try opening AT&T in a new InPrivate window.

If that doesn’t work, disable all browser extensions and flush your DNS by running ipconfig /flushdns in PowerShell, then restart your router.

We just moved into an Independent Senior Living Community on August 1st and we have our internet through the Community. They set is up for us and I do not know if it is set up the same way as it was when we were living in our home. Another question: what is blacklisted? I am not using a VPN/proxy and I have cleared the cache and cookies. I tried re-opening in a new InPrivate window but I still get the error from AT&T. What I don't understand is why is this only affecting my AT&T website. I am having no other problems with any other website? I can disable all browser extensions but don't know what PowerShell is.

If your network is managed by the community IT, then you should contact them, as it is possible that they have set certain rules for internet usage. This could be the reason you are having trouble accessing this site. Each site has specific requirements and can be blocked individually, so the fact that other sites work normally is not a guarantee that the issue isn’t related to the network settings.You can also test this by using a mobile hotspot from your phone and connecting your device through it. If you are able to access the site that way, it means there are network settings that the community IT must change in order for you to access the AT&T site

Too technical, I'm 78 years and don't know how to do this. And yes, this just started this week. I've used Edge and Chrome on Windows 11. No luck.
