SSIS TO SALESFORCE Could not establish trust relationship for the SSL/TLS secure channel

Using the Salesforce source connector in SSIS supplied by Cozyroc in Visual Studio 2019. This was working perfectly until a week ago and then started getting the following error:

Error: System.Net.WebException: The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel

I have contacted both Cozyroc and Salesforce who have directed me to contact Microsoft.

Any help would be appreciated.

    Hi @Billy Blue ,

    The issue might be that:

    You're using an invalid certificate:

    The certificate wasn't issued by a trustworthy authority.

    Try to navigate to the service URL using a browser and have a check.

    Here is a same thread you may take a reference to : https://social.technet.microsoft.com/Forums/msonline/en-US/f9aee5bb-d307-4782-9633-adc29fd10189/ssisssdt-the-underlying-connection-was-closed?forum=sqlintegrationservices

    Regards，
