maybe your csi driver is not healthy， please check the "sock"

I'm having the same problem. @GongWilliam any info on how to solve it? I already checked the csi-sock but I don't think that's the issue, my csi driver is responding to GRPC call: /csi.v0.Identity/GetPluginInfo like yours, but not to GRPC call: /csi.v0.Controller/CreateSnapshot :/
