Hi, I can't link my bank account, I keep getting error code OBA28, how can I solve this please?

Hello there, useremmaberrys.

The error indicates that your bank requires PINsentry to be used when upgrading your existing bank feed to open banking or connecting a new account in QuickBooks Online. To get rid of the error code OBA28 and connect your bank successfully, you'll need to utilize the PINsentry token.

If you've already used the token, and get the same thing, you can perform a few browser troubleshooting steps. Try logging in to your QuickBooks Online account in an incognito or private browser. After logging in, go to the banking section, and link your bank account. If it's connected, go back to your regular browser and clear the cache. Clearing the cache resolves any common browser-related errors. Other browsers can also help you get rid of unexpected responses from your main browser. 

Let me know how this works. I'd be more happy to help you. Take care and have a great one!
