Calling either the restore_factory or restore_defaults in conduit firmware version 5.1.6 via the conduit API results in unknown command error as mentioned below.

Here is the raw get request logged in fiddler

{
   "code" : 400,
   "error" : "unknown command",
   "status" : "fail"
}

This used to work and all of a sudden it’s throwing this error, when called via the API.

Thanks,
