Error message keeps showing when trying to link bank account

I want to make certain that I provide you with the appropriate resolution, @meganlamont21-gm.
 

Could you please tell me the name of your bank and the error message you received when attempting to connect it to QuickBooks Online (QBO)?

This allows us to narrow down the problem and provide you with a quick solution. Any additional information will be greatly appreciated.

I'll be here waiting for your response.
