Apparently with no code changed I just started to receive an "connection denied" error, no sale is working now. The following is returned by the JS SDK:
{name: "CloverError", code: "connection denied", message: "D12FJD4DRSPRV", cause: undefined}
Is there a problem with Clover API? How can I troubleshoot this?
This indicates that there is an existing connection to the device, identified by D12FJD4DRSPRV. When a connection is made to a device, it is possible to set a 'friendlyId' using the configuration passed to the Clover() object. If this is not set, then an id is generated and used. In this case the 'friendlyId' of the connection that is reportedly currently connected is D12FJD4DRSPRV.
