I have a C-Store SCU that only sends DicomCStoreRequests which need to be rejected during negotiation.
Using AddRequestAsync to add n DicomCStoreRequest and sending the storage request with SendAsync.
The recipient rejects them correctly, but SCU returns, for the same DicomCStoreRequests, sometimes Successful and sometimes Failed. This is because sometimes it enters into OnResponseReceived event and receives an error and sometimes it doesn't enter the event.
I'm probably making a mistake while receiving the response and need some additional information about the library.

Thank you so much for your support.

Please post some sample code. Where does the SCP reject the request? On AssociationRequest, so that the C-Store requests should not be sent over the network? Or is the SCP rejecting some of the instances and accepting some others?

In the SCP the Transfer Syntaxes of the images sent has been disabled, therefore during the AssociationRequest. So when I send these images, sometimes I get an error, because it goes into the OnResponseReceived event and sometimes not, because it doesn't go into the OnResponseReceived event

so you say, that the StoreSCP rejects some of the Transfer Syntaxes. Rejected instances will not be sent and therefore there will not be a OnResponseReceived event, because if they are not sent, then there will not be a response. Or did I get you wrong?
As said, some code or some logs would be helpful.
