How to fix in AT&T Yahoo Mail: oidc.idp.clogin.att.com

Thank you so much. All excellent suggestions, which I have tried, many times.

All of a sudden the answer came to me. I have been signed into my account on the iPhone and my iPad. Once I signed out of these, I was able to access my desktop Yahoo email account.

I believe this is the solution, at least until the next time it happens. 

Here are a few things you may try if you're having trouble using the Google browser to access AT&T Yahoo Mail on your Windows 10 desktop and getting the error notice "oidc.idp.clogin.att.com unexpectedly closed the connection": Verify your internet connection. Make certain that your machine is online and that your connection is strong.

To determine if the issue is unique to AT&T Yahoo Mail or a more general connectivity issue, you might try visiting other websites.

Disable any VPN or proxy: whether you are using a VPN or proxy, try temporarily turning it off to see whether this affects your ability to access AT&T Yahoo Mail. These services occasionally have the potential to disrupt the connection. Delete browser cache: Deleting the cache in your browser might help you fix problems.

Clear your browser's cache: Doing so can assist in resolving difficulties with cached data. Click the three dots in the top-right corner of Google Chrome, choose "More tools," and then click "Clear browsing data." Be careful to choose the option to remove cached files and pictures.

Try a different browser: If the problem still exists, try using Mozilla Firefox or Microsoft Edge to access AT&T Yahoo Mail. Such errors can occasionally be brought on by browser-specific problems.

Temporarily disable PC Matic: As a security programme, PC Matic may contain settings that prevent access to particular websites. To see if it helps, try temporarily turning off PC Matic or adding an exception for AT&T Yahoo Mail.
