Excel dd-in isn't workin after setting SSL only access in ALM?

Hello, We have an issue where the SSL only access has been installed on our system and the results is that now everyone can access with the browser and explorer without issue but those needing to utilize the Excel add-in are not able to authenticate. We are receiving an error that states that the "Authentication is not authorized and verify that the URL is correct." Is this a known issue when going to SSL only authentication using TLS 1.2 in ALM 12.53? Thanks, HomerJ
