VxRail 7.0.410-27831807: Can't enable Support Connectivity

Hi all,

We have installed a 3-node VxRail cluster with integrated vCenter. All is working fine, but for some reason I can't configure Support Connectivity. I've tried both the Direct Connection and a Secure Connect Gateway.

Regards,

Erwin G.
