http error 431 with Bank of America AND Discover - how to fix?

Question

I just purchased Quicken again (used 5 years ago) BUT right away I cannot update these accounts.  What is the fix?

Maybe this is related to this Alert?: NEW! 2/24/26 Bank of America Migration (multiple BIDS). Also, and maybe tied to this Alert as well and/or to the local system: Google's AI returned the following message regarding Error 431. HTTP Error 431 ("Request Header Fields Too Large") occurs when a web browser sends a request with headers (often cookies) that are too big for the server to process. To fix it, clear your browser’s cache and cookies for that site, try using an incognito/private window, or restart your browser. Common Causes and Fixes: * Too Many Cookies: The browser has stored too much data for a specific domain, causing the header to exceed server limits. * Fix: Clear cookies for the specific website or all sites via browser settings. * Long Referrer URL: The link used to access the page is too long. * Browser Specifics: For Chrome, resetting settings to default or flushing DNS (ipconfig /flushdns in Command Prompt) may help. For Website Owners/Developers: If you own the server, you may need to increase the maximum allowable header size in your web server configuration (e.g., Apache or Nginx) or reduce the number of cookies your site sends.

* Thank you for your prompt reply.  here are my answers:
* The quicken files is located on an external hard drive:  E:\PERSONAL Files\Personal Files\Quicken Files\QDATA.QDF.
* VPN is OFF
* first started with my recent purchase within the past week.   I just purchased this software.  I used this 5 years ago.  I am using the last Quicken file.  I deleted the Bank of America account and reloaded it.   I added as a new credit card, the Discover credit card and it gives me the very same message.    
* No anitvirus or malware except for Microsoft.  I have Microsoft 10 on  my computer
* here is the screenshot .  I receive the SAME screenshot for both Bank of America and Discover

* If I cannot fix this, I want my money back as I am in my 30 day window, still.
