An error will be generated if SHA-1 is used in the ATS environment, therefore you must switch to SHA-256 or higher. Additional information can be found on the MeF Status page on IRS.gov. Note:  This update will also apply to the 2021 production submissions. We apologize for any inconvenience this change may cause.
