OL-301 is one of several general connectivity errors with the server that can occur for a number of reasons. For example, your financial institution's online services may be down due to server maintenance, high server traffic, stock market hours, or an unexpected outage.
This error can also occur if you attempt to use an online service in Quicken that is not enrolled with your financial institution. This scenario most frequently occurs with bill pay services with the financial institution that are enabled in Quicken but have not yet been enrolled/registered for Quicken data transmission with the financial institution.
If you have just upgraded from to the new version of Quicken use article SLN74045 to resolve this issue.
Wait a couple of days and also try updating your account during different time of the day (some banks perform regular maintenance at the same time every day).
The error message you receive is a generic message generated by your financial institution.
Look in the One Step Update Summary for a message from your financial institution.
If you have waited and the problem continues, delete your temporary internet file and try again.
To delete the files in the Temporary Internet Files folder:
Windows 7 / Vista
Earlier versions of Windows
If this error occurs when trying to send online payment:
If you are able to update accounts without sending a payment, but receive the error when sending an online payment through the financial institutions bill pay service, you must contact the Online Banking Support for the financial institution to ensure that you have enrolled your Quicken program to connect to their bill pay service and that you have an active bill pay service with them.
To find the contact information for your financial institution, go to Tools > Online Center and click Contact Info at the top of the window after selecting your institution name.
Quicken Support would not be able to resolve this specific error, as we do not have access to your accounts on the financial institutions servers in order to confirm your status.
