Hi info2298, Thanks for reaching out here in the Community.
To star with, could you please let us know if you encountered any error messages while attempting to connect your bank? Any additional details about the situation would be greatly appreciated, as they could help us provide a more precise resolution.
To successfully connect your bank to QuickBooks, please make sure that your login credentials are entered correctly.
If you've verified that the credentials are correct but still experience issues, I recommend reaching out to your bank to check if there are any notifications, restrictions, or ongoing maintenance activities on their end that might be causing the problem.
For further guidance, you can refer to this article to learn more about resolving banking errors: Troubleshoot and fix banking errors.
