You are importing a .qbo file from an approved financial institution in QuickBooks for Mac and you get the following error.

OL222

OL-222 error indicates that QuickBooks did not receive a valid response from the financial institution's server. A parsing error occurred in the server response. This is often caused by one or more characters in the .qbo file that are not compliant with the Open Financial Exchange (OFX) standard for exchanging financial data with QuickBooks.

This may also happen if the download (.qbo file) is formatted incorrectly and needs to be fixed by the Financial Institution.
