OHIF Viewer : Couldn't connect to Orthanc Server

Describe the bug I am trying to use OHIF viewer. When trying to run monailabel start_server --app apps\deepedit --studies http://127.0.0.1:8042/dicom-web this URL , it pops up with a dialogbox to enter the username and password.

I tried some default username and password, but it doesn’t signed into the Orthanc Server.

To Reproduce Steps to reproduce the behavior: For this, I followed the below steps which was mentioned in the document.

1. Installed Orthanc using apt-get install orthanc orthanc-dicomweb.
2. Upgraded to latest version by following steps mentioned here

Now the orthanc server setup is completed.

1. Run the command monailabel start_server --app apps\deepedit --studies http://127.0.0.1:8042/dicom-web

Expected behavior

I expect that orthanc server should load without the authentication pop up.

Additional context I installed the orthanc in DGX docker container.

Any suggestion and help is appreciated. Thank you

Hi @Suchi97,

Once you redo the installation for Orthanc you might want to update a few fields in its configuration (/etc/orthanc/orthanc.json). To disable authentication you can set

"AuthenticationEnabled" : false,

but that’s not sufficient if your orthanc server isn’t on the same machine (or container) as the label server, s you’ll have to set

"RemoteAccessAllowed" : true,

and make sure that

"SslEnabled" : false,

If you don’t want to disable authentication to Orthanc, you can setup your own user

"AuthenticationEnabled" : true,
"RegisteredUsers" : {
    "orthanc" : "orthancpass"
  },

Furthermore you will want to double check that your dicomweb module is enabled, and that the configuration file exists (e…g /etc/orthanc/dicomweb.json). If you have a dicomweb config like

{
  /**
  * The following options control the configuration of the Orthanc
  * plugin adding support of WADO and DICOMweb.
  **/

  "DicomWeb" : {
    "Enable" : true,         // Whether DICOMweb support is enabled
    "Root" : "/dicom-web/",  // Root URI of the DICOMweb API (for QIDO-RS, STOW-RS and WADO-RS)
    "EnableWado" : true,     // Whether WADO-URI (aka. WADO) support is enabled
    "WadoRoot" : "/wado",    // Root URI of the WADO-URI (aka. WADO) API
    "Host" : "localhost",    // Hard-codes the name of the host for subsequent WADO-RS requests
    "Ssl" : false,            // Whether HTTPS should be used for subsequent WADO-RS requests
    "Servers": {
      "local": {
        "Url": "http://localhost:8042/dicom-web", 
        "Username": "orthanc", 
        "Password": "orthancpass"
      }
    }
  }
}

you should be able to check the URL: http://localhost:8042/dicom-web/app/client/index.html to see if your DICOMweb service is enabled and working.

As @SachidanandAlle explained you will have to set the args for username and password in version 0.2.0 or setup the env vars for 0.3.0.

You can also check whether things are working for you with dicomweb using

curl -X GET -H "accept: */*" -u orthanc:orthancpass http://localhost:8042/dicom-web/studies
