DUL network read timeout

Hello,
I need some help with solving the problem. About two months ago, I installed Orthanc. DICOM images were uploaded to the server from two mammography units and an X-ray, and viewed on workstations. Recently something has happened, and at the time of uploading images from the devices to the server, viewing through the Radiant Viewer became unavailable (results are not loaded, occurs an error in the logs “Receiving Association failed: DUL network read timeout”). I will be very grateful for your help. I attach logs, logs in the --trace mode, packet capture via Wireshark, and a screenshot from the Radiant Viewer.

Thank you so much,
Mikhail

Hi,

The connection to the node is working? (you can check with telnet)
If you have a bad network, you can configure the timeout with DicomScpTimeout and DicomScuTimeout. Default is 60s.
It may take some time to transfer big dataset.

Hi!
The connection to the server works without problems. I tried to configure DicomScpTimeout and DicomScuTimeout, and it didn’t help. The speed of our network connection is 1 Gbit/s.

Hello,

You should try to identify what changed in your configuration that led the images not to be received anymore.

Have you upgraded one component of your network devices, has your system administrator changed a network parameter, has some firewall been added, have you upgraded the version of some software/hardware,…?

The “Receiving Association failed: DUL network read timeout” indicates a problem with your network infrastructure. Try to run Orthanc on the same computer as RadiAnt, and to turn off all of your firewalls for testing. Also, carefully follow the troubleshooting guides:
https://book.orthanc-server.com/faq/dicom.html

In either case, you’ll most probably have to hire a professional who could test and debug your infrastructure:
