A few questions:

1. Are you using this component or the out of the box sharepoint connector?
2. If this is an on-prem set up, are you using a self-signed cert to connect?

If you are using this component, it does not support self-signed certificates. If you are using the out of the box connector, you should be able to upload the cert into trusted certs in the admin console.
