Thank you for posting on this thread, @propertyservices.

I appreciate you following the steps provided by @MarsStephanieL and I'm here to help you further.

Did you try it by first launching your browser in the Incognito or InPrivate mode?  If you're using a Windows machine, typically right-clicking on the browser icon will give you the option of a Private window.

Here are some possible causes of error 163 in QuickBooks: 

1. The error is also triggered by the cache and junk files present in the browser you are using to access QuickBooks Online banking.
2. Poor internet connectivity or no internet connection.
3. If your banking info like the website, routing number, or account number is changed.
4. Banking website temporarily down for maintenance.

To fix this issue, let's first use an incognito or a private window to confirm a browser-related problem. Follow these keyboard shortcut keys below: 

• Google Chrome: press Ctrl + Shift + N  
• Mozilla Firefox: press Ctrl + Shift + P
• Safari: press Command + Shift + N

If it's working fine, you can clear your browser's cache. This will delete your temporary browsing history, thus, fixes QBO issues. Accessing your account using a different browser can be an option, too. Once done, go back to your home page and check your dashboard and your create button.
