Tenable Security Center Integration API Issues

Self signed cert for Sec Center. The ssl side of the house seems to be fine as the agent is fully healthy. Generated the access/secret key in sec center with an administration account and enabled allow api keys in the gui.

When I curl it with the asset/secret key, I get a token not authorized error and I am seeing a 403 error on the most recent elastic logs. It won’t even allow me to curl to /rest/status. When I just run curl -k to verify 443, that does work but the other curls are the keys do not. Anyone have any idea? Thanks.
