DFU Update fails to Connect on iOS error 94

[RyanTemp]

Using;NRF52832,

SDK17,

Flutter 3.10.5 ,  

nordic_dfu: 6.0.1,

iOS 16.5.1

iPhone 14 Pro Max

Using my developer device I can successfully update DFU,

However on my QA team device they consistently get an error 94

message: DFU Error received on device A7088E16-715D-F7D6-8B84-E8F3E02DF3E4, error 94, error type: 94, message: Operation failed

She can update using the Nordic DFU iPhone app ,and also using her Android device

Where can I see the meaning of the error codes, and any other advice will be appreciated

We managed to resolve this by rebooting the iPhone, perhaps turning on and off the Bluetooth may have worked also.

I would still like a response on how to decipher error code and how frequently we can expect to see this error.
