Orthanc crashes on startup after DicomWeb configuration - Ubuntu 24.04

General

Orthanc systematically crashes on startup when I add the DicomWeb section to the configuration. Without this section, Orthanc starts normally, but I can’t connect from OHIF Viewer.

Configuration:

OS: Ubuntu 24.04

Orthanc: Installed via apt install orthanc orthanc-webviewer orthanc-dicomweb

OHIF Viewer: Latest version

Orthanc configuration file (/etc/orthanc/orthanc.json):

{“Name”: “Orthanc”,“StorageDirectory”: “/var/lib/orthanc/db-v6”,“HttpServerEnabled”: true,“HttpPort”: 8042,“DicomServerEnabled”: true,“DicomAet”: “ORTHANC”,“DicomPort”: 4242,“RemoteAccessAllowed”: true,“HttpHeaders”: {“Access-Control-Allow-Origin”: “*”,“Access-Control-Allow-Methods”: “GET, POST, PUT, DELETE, OPTIONS”,“Access-Control-Allow-Headers”: “Authorization, Content-Type, Accept, Origin”},

“DicomWeb”: {“Enable”: true,“Root”: “/dicom-web/”,“EnableWado”: true,“WadoRoot”: “/dicom-web/”,“Host”: “localhost”,“Port”: 8042,“StowMaxSize”: 0,“AllowOrigin”: [“http://localhost:3000”],“AllowDelete”: true
}

Hello,

Here is what I tested:

# start a new ubuntu "machine"
docker run -it ubuntu:24.04

apt-get update && apt-get install -y orthanc orthanc-webviewer orthanc-dicomweb nano
mv /etc/orthanc/orthanc.json /etc/orthanc/orthanc.json_orig
nano /etc/orthanc/orthanc.json
#paste the modified config file and save

Orthanc /etc/orthanc/orthanc.json

Orthanc starts correctly …

Modified config file:

{
	"Name": "Orthanc",
	"StorageDirectory": "/var/lib/orthanc/db-v6",
	"HttpServerEnabled": true,
	"HttpPort": 8042,
	"DicomServerEnabled": true,
	"DicomAet": "ORTHANC",
	"DicomPort": 4242,
	"RemoteAccessAllowed": true,
	
	// inexistant config, probably an AI hallucination !
	"HttpHeaders": {"Access-Control-Allow-Origin": "*","Access-Control-Allow-Methods": "GET, POST, PUT, DELETE, OPTIONS","Access-Control-Allow-Headers": "Authorization, Content-Type, Accept, Origin"},

	"Plugins" : [
		"/usr/share/orthanc/plugins/"
	],
	"DicomWeb": {
		"Enable": true,
		"Root": "/dicom-web/",
		"EnableWado": true,
		"WadoRoot": "/dicom-web/",
		"Host": "localhost",
		"Port": 8042,
		"StowMaxSize": 0,
		
		// inexistant config, probably an AI hallucination !
		"AllowOrigin": ["http://localhost:3000"],

		// inexistant config, probably an AI hallucination !
		"AllowDelete": true
	}
}

Hope this helps,

Alain
