Hi, 

I have installed version 1.0.0b2 using Docker on a Windows PC and have connected it to our hospital's Test PACS. 

I am having some trouble connecting to the built-in Orthanc database for query-retrieve. 

I am using the default Port 104, but receive a server down error:

Port 104 error.jpg

The docker-compose.yml file is configured as such:
# DICOM store port (first number)
      - 104:4242

And the Orthanc web interface is enabled. 


I would be very thankful for any help. 

-Harry

Hi Harry,

Just to make sure we’re not overlooking anything — is the Docker container name orthanc_1 or openrem-orthanc-1?

Best regards,
Orso

Hi Orso, 

Thank you for your suggestion. However, even with this change, I still get that error.

Strangely, when I try port 4242, I get a success status, but I don't think that is correct.

The code make it clear that the port that should be used is the first number in the yml:

# DICOM store port (first number)
      - 104:4242

And I think it causes a C-MOVE error when I query-retrieve:

Thank you

Dear Harry, 
I suggest to try 

# DICOM store port (first number)
      - 4242:4242.
You must bring the docker down and up after the changes. 
BW,
Orso

I'm wondering if the Windows firewall is blocking incoming port 104 - have you reviewed that?

I haven't done this recently on Windows, but it could be that a privileged (low) port like 104 is blocked unless you open it, and a high port like 4242 might not be.

There are instructions for a native Windows install on firewall permissions here: Native Windows install — OpenREM 1.0.0b3 documentation
