Failed to get response from server error while trying to connect to Dynamics 365 using linked services – Azure Data Factory

Recently, while trying to connect to Dynamics 365 data set through Linked Service

we got the below error

Seems like a product issue, so the workaround is

Opening Azure Data Factory in a new incognito or in-private mode.

Or

Cancel and do not select the certificate, while testing the connection.

Ignoring the certificate fixed the issue for us.

Hope it helps..
