Hello All, Emily Griffin here, I work in customer support. Numerous Quicken customers are curious as to what causes the 'Quicken error cc-OL-301-A.' When attempting to connect to a financial institution using Direct Connect, the OL-301 error occurs. The circumstance may eventually necessitate the implementation of a remedy by the financial institution. This is a frequent occurrence with Quicken 2016, 2017, and 2018. This may be caused by an incorrect Quicken installation on the machine, a virus, or certain issues in the Quicken files. Malware issues can too lead to the error message.
