Bank account does not link to QuickBooks anymore and continues to fail to link each time I try.

Hi denverdebes,
 

Welcome to the Community. Having your bank connected to QuickBooks Online is essential to keeping your books up to date. I'd be glad to point you in the right direction to get the support you need regarding the banking connection. 
 

A banking connection problem can be caused by browser cache and cookies as they can prevent the system from functioning efficiently. I encourage you to take the following steps to perform browser troubleshooting
.

• Clear browser cache
• Try in a private browser window
• Use another browser type
• Make sure you're using supported browsers
• Turn off any ad and popup blockers temporarily.

If the steps provided above don't work, I recommend that you contact our customer support team as they can have a closer look at how to resolve this. Here are some options available to reach out to our team.

Schedule a Callback or start a Chat: click (?)Help in the upper right in QuickBooks Online > type and enter "Contact support" into the QB Assistant > click Contact Us > explain your situation > click Let's Talk > choose Get a callback or Start a Chat.
Social Media: Facebook, Twitter, and Instagram. Support hours are from Monday to Friday between 9 a.m. and 8 p.m. ET

Feel Free to reach out if you have any questions, I'll be happy to help.
