When trying to e-file a return in ProSeries, you may receive the following message:
An error occured in the secure channel support.

Understanding secure channel errors
Secure channel errors may occur if you haven't enabled Microsoft Edge browser settings to use the correct version of the Transport Layer Security (TLS) protocol.
Lacerte products no longer support the TLS 1.0 protocol. As of 2018, many ProSeries products, including prior years, have been updated to reflect this change.
Update all versions of ProSeries products to make sure they have the latest TLS protocol available.
How to enable the correct version of TLS:
- Close ProSeries.
- In the Windows Taskbar, enter Internet Options.
- Select Internet Options.
- In the Internet Properties window, select the Advanced tab.
- Scroll to the Security section.
- Select the box labeled Use SSL 3.0.
- Select OK.
- Open ProSeries and try to e-file, check acknowledgements, or license.
