Hello there, @KAPPHOTOS.
I appreciate all your efforts in trying to move past the error. I'm here to help ensure you can log in to your account.
Before we begin, may I ask if you have multiple QuickBooks Online (QBO) subscriptions? If so, make sure that you sign in to the right one and input the correct login credentials. This guarantees that you can access the program seamlessly.
If you continue to get the same result after entering the right username and password, I recommend contacting our QBO Care Team for further assistance. They have extra tools to determine the source of this error. When a permanent solution becomes available, our specialists will take you through the implementation process.
To get the contact details:
- Go to the Help icon at the top to display the Search window.
- From there, click the Contact Us link to access the What can we help you with? section and then enter a brief description of your concern in the field box.
- Tap the Continue button to see the list of support options.
- Pick Chat to start a conversation or Callback to speak with an agent.
I also attached a link that tackles the various login issues and errors in QBO: Learn what to do if you can't sign in.
Additionally, these resources include various topics on how to better handle your accounting activities and troubleshoot common errors:
Reach out to me again if you have other QuickBooks concerns or need further assistance logging in to your account. I'll get back to help you the best that I can.
