When I am sending a DICOM file(size 557MB) from local Orthanc to live Orthanc server then after 10 minutes sending failed and showing 500 Internal Server Error.
What happens if you send the same files to a local Orthanc ?
From other posts you made on the same topic, I think you have an nginx in front of your server so nginx might be interrupting the connection after 10 minutes or limit the size of HTTP requests …
So please, first test locally to check if it’s an Orthanc issue.
