Error 350 - Continues to occur although we have reconnected several times. How do we fix this issue?

As of a couple of weeks ago we continue to get Error 350 regardless of our reconnecting to the bank. How do we fix this long term?

Hi there, @E2MBeancounter. I agree with what @SIAB mentioned. Opening QuickBooks Online (QBO) in an incognito/private window helps bypass cached data or old login tokens that may block the new bank authorization. Once you're in the private window, reconnect your bank so that QBO can establish a new connection.

You can also check your bank's website for any alerts or updates, as changes on their end can cause the 350 error to continue.

If you have follow-up questions, please don't hesitate to click the Reply button.

Try opening your QBO account on any private/incognito browser.

This has not been solved. I spoke with a QuickBooks rep this afternoon who admitted that there is a known issue with Bank of American and QuickBooks subscribers with multiple company accounts and multiple bank accounts. My supervisor who is the account holder will now have to contact QB to screenshare and troubleshoot it together. I sure hope they can come to some type of resolution.

Thanks for the update with more specific details, E2MBeancounter. In case this requires more time to resolve, consider manually uploading transactions from your affected accounts. This way, you can continue working on your books while waiting for a fix.

Please note that once the connection is restored, those same transactions may download automatically. If that occurs, be sure to exclude them to avoid duplicates.

Feel free to return if you have follow-up questions.
