Hi,

Could you please give us a URL of the website you experience troubles with?

Hi Denys, sorry 4 delay. Managed to find (what I think is) the URL: oidc.ipd.clogin.att.com

b/g info: this is AT&T login, but anything AT&T is similarly blocked. Other sites also (eg: subscribing to an NGO - is blocked for the same. reason (I think).

It is probably relevant that I am a US resident with a US phone. I'm in the UK caring for a sick relative.

Further info: trying to resolve the issue, I have fiddled with three iDevices: the phone; a MacBookPro running on Sequoia 15.5; and an iPadOS version18.5

...and the whole shebange is synchronized!

Hope that can help and thank you for your kind attention. Harry (North)

Thank you for the detailed reply!

That URL does not load on my devices (in both Firefox and Chrome/Edge) as well (I live in Poland). I believe it's just wrong/misspelled/deprecated.

However, att.com loads normally, and it correctly redirectes me to the sign in page (https://signin.att.com/dynamic/iamLRR/LrrController?IAM_OP=login&appName=m14186&loginSuccessURL=https:%2F%2Foidc.idp.clogin.att.com%2Fmga%2Fsps%2Foauth%2Foauth20%2Fauthorize%3Fresponse_type%3Did_token%26client_id%3Dm14186%26redirect_uri%3Dhttps%253A%252F%252Fwww.att.com%252Fmsapi%252Flogin%252Funauth%252Fservice%252Fv1%252Fhaloc%252Foidc%252Fredirect%26state%3Dfrom%253Dnx%26scope%3Dopenid%26response_mode%3Dform_post%26nonce%3D6XRuzE3j).

Did you refer to that website? If so, what happens when you click Sign in?

Can I send you a screenshot? I'll try...

Sorry I just don't know enough. This is the address I get:

     https://signin.att.com/dynamic/iamLRR/LrrController?IAM_OP=error&Referer=https:%2F%2Fsignin.att.com%2F
   With the message: AT&T.  It's not you, it's us.   We can't complete your request right now, please try again.
  ... with an OKAY button

This is way over my head. Thanks for trying. HN

Hope you don't lose patience with me. I've included an image below (screen shot)
