Error message 101 when trying to connect bank account to QuickBooks. Have already called bank and all is fine on their end.

Hi there, @usermattneal.

Connecting your bank account is my top priority. That way, you can manage and track your bank transactions in QuickBooks Online (QBO). 

I appreciate you for calling your bank and answering the security questions. Normally, the error 101 appears if the browser is full of cache and cookies. 

With this, I'd suggest performing primary troubleshooting steps to isolate the error. To start, please access your account via incognito. These browsers won't save any browsing histories. 

Feel free to use these shortcut keys:

• Google Chrome: Ctrl + Shift + N
• Safari 11 or newer: ⌘ + Shift + N
• Mozilla Firefox: Ctrl + Shift + P
• Microsoft Edge: Ctrl + Shift + P

Once logged in, re-connect the bank to verify it's already performing adequately. If you're able to do so, we'll have to go back to your normal browser and clear the cache to drop the junk files. Using other supported browsers is a good option also.

Once the bank account is connected, your recent transactions will automatically be downloaded into the system. Please go to the Banking tab and hit Update to show the data in the For Review. 

After that, categorize the data to avoid any duplicates. For more information, check out this article: Categorize and match online bank transactions in QuickBooks Online.

I've also added some articles about handling credit card transactions, reconciling accounts, and other topics. 

• Learn about the chart of accounts in QuickBooks
• What to do if you get a bank error or can't download transactions
• Reconcile an account

Let me know if you have follow-up questions. I'm eager to help. Keep safe always.

Try opening your account on private/incognito browser and redo the process. If the same error persists, utilize the trial period of SlickConnect to isolate the issue if it supports your bank.
