Download images serie

Hi everyone.
I’m having trouble downloading large images. I can’t identify them, and I’m stuck.
I have Orthanc and Ohif running in Docker, and the Nginx proxy manager to view with Ohif. The only thing I have enabled is HTTP/2.
It sometimes seems to freeze, and the operation is erratic. I restart the VPS and it works fine. But trying to find the fault, which I don’t know what it could be, I saw that the images are requested in parallel, but they download serially. One finishes and the other continues, and so on. I don’t understand why they don’t all download at once, like in the case of mammograms. I think they should download them all at once, which would speed up the viewing process significantly.
That’s one thing. And then, I don’t know why there are times, or after a few hours, sometimes days, it seems like the download slows down… I restart the VPS and it works perfectly… I don’t understand.
Any recommendations are welcome.
The VPS isn’t overloaded; it has 8GB of RAM, 2 CPUs, and 2TB. It’s never at 100%, it’s always asleep.
I don’t know why the images can’t download in parallel or what I should configure, and if it’s in Orthanc, the configuration.
I’m leaving a photo and my Orthanc configuration.

Hello,

Unfortunately, your setup involves multiple components (Orthanc, nginx, OHIF, VPS), so nothing proves that Orthanc is the culprit here. You’ll have to provide a minimal working example so that other people can independently reproduce and investigate your issue.
