Welcome to the Community!

I appreciate your effort in attempting to resolve the error by performing the troubleshooting steps, Charlotte. Error 108 usually means your bank or credit card company has posted a notification on its website that requires your attention.

These notifications are often related to updates from your bank, including:
 

• Changes to terms of service
• Maintenance schedules
• Promotional offers
   

Keep in mind that these messages can prevent QuickBooks from connecting to your account.
 

After you address the message from your bank, make sure to update your bank connection in QBO.
 

If there’s no notification from your bank but the error continues, I suggest contacting your bank to check for additional messages. If the problem persists, you can use an incognito or private browser to log in to QuickBooks.
 

Don’t hesitate to revisit this thread if you have additional questions.
