XNAT Desktop Client | HTTP/Web Proxy

[Jerico Revote]

Hello Team,

We're trying to use the XNAT Desktop Client inside

a "Safehaven" Windows instance. This instance has no

access to the internet (by default) due to security controls.

We do use HTTP proxy to enable our apps (e.g R/Python)

to pull down relevant software/library packages from external source (e.g internet/github).

The HTTP proxy settings are configured as per standard

environment variables on Windows.

We've already allowed our XNAT endpoint/server in our HTTP proxy,

and in fact, we can connect to this endpoint within the instance,

using other interfaces (e.g python/xnat-utils). But when trying to login

to the XNAT endpoint via XNAT Desktop Client, we get this error:

"Login failed!"

Please check XNAT server address (and your internet connection).

It looks like XNAT Desktop Client doesn't detect our HTTP proxy settings.

Is there additional config/settings we have to use to use

the desktop client behind a proxy? Thanks.

Regards,

Jerico

As best I can tell, there isn’t any way to get the desktop client to use a proxy at this point. The underlying frameworks–node.js and Electron–are a little weird about controlling behavior via environment variables because, by their nature, it can be hard to determine what the environment is. The library that the desktop client uses for HTTP/REST calls lets you configure an HTTP agent that can include, amongst other things, a proxy configuration, but that requires explicit coding to support that and that’s not in there. I created an issue for this, so hopefully this is something that can get into an upcoming release.
