Looks like ONTAP Edge has lost connection to the Vcenter. Try to log into the Edge VM and with the DIAG mode see what credential is used to connect the the vCenter server. Update the credential if required.
You could create a read only user on the host, and have edge log in to its host directly. There is no need for it to have credentials in vcenter, since it is permanently bound to its host. This way sysconfig -p will be operational, and the warnings will go away. Even without access to its host it will still serve data, it just will not have any awareness of the underlying physical infrastructure, storage, etc and any related commands will not work.
