Hello, @cadet001. 

We recently had an issue with logging into QuickBooks Online. However, this was already closed and resolved. Since you’re still unable to log in to the account, I suggest clearing your browser’s cache.

Check the following article for detailed guidance: Clear your browser cache and temporary Internet files. 

You can also use other browsers like Chrome, Safari, Edge and the like if you're unable to log into your account in the browser that you're currently using.

Let me know if you still need help with logging in to your account. I'm always here to assist.
