Dear All,
I have a working Orthanc setup running on [dicom.mydomain.com](http://dicom.mydomain.com) where everything has been working great for past three years, including loading of images with OHIF v2.
I am trying to upgrade to OHIF v3. The first GET works OK (200), the following ones get an error of 404.
I have copied the Dicom-Web configuration below. Any help would greatly appreciated.
Current Orthanc is 1.11.2.
“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” : “[https://dicom.mydomain.com/orthanc/dicom-web/studies](https://dicom.mydomain.com/orthanc/dicom-web/studies)”, // tried → “”, “orthanc/dicom-web” Hard-codes the name of the host for subsequent WADO-RS requests
“PublicRoot” : “”, // tried → “”, “/orthanc/dicom-web/studies”, “[https://dicom.mydomain.com/orthanc/dicom-web/](https://dicom.mydomain.com/orthanc/dicom-web/)”,
“Ssl” : false, // Whether HTTPS should be used for subsequent WADO-RS requests
“StudiesMetadata” : “MainDicomTags”, // How study-level metadata is retrieved (since release 1.1, cf. section below)
“SeriesMetadata” : “MainDicomTags” // How series-level metadata is retrieved (since release 1.1, cf. section below)
}

Hi,
If you check the Orthanc logs in verbose mode, you should see what URL is being called and return the 404. It should help you understand what’s wrong in your configuration (be it the IIS config or the DicomWeb plugin config).
HTH,
Alain
