Nothing reported in ONTAP. Get this in the app "The request signature we calculated does not match the signature you provided. Check your key and signing method." Except the keys are fine and the v4 signing is selected. So something is different between 9.9.1 and 9.10.1. Was hoping others may have discovered this and knew the solution. Either I have to do something different to connect to this version or there is a bug. Will contact NetApp.
