Hi
I have a Orthanc Server running in EC2 as a image forwarder. I keep getting the following error frequently without any image being sent to the Orthanc Server.
The frequency of this error is irregular and comes up several times a day.

CommandDispatcher.cpp.284] Receiving Association failed: Unrecognized PDU type: 47

I have looked in the forum but all other cases are linked to an action being done. In my case it is coming without any action.
I dont understand the reason for this. Can anybody advise?

Regards
Kavi

Hello,

This seems to indicate a problem with your network connection.

If this is not the case, please provide a minimal working example so that people can independently reproduce your issue:

Hello,

As answered above, an error similar to:

indicates that a DICOM connection was opened against the HTTP port of Orthanc. It is typically encountered when typing:

$ storescu localhost 8042 sample.dcm

Such an error can be solved by replacing 8042 (the HTTP port) by 4242 (the DICOM port).
