Extensions index is down?

For example, this does not work:

https://slicer-packages.kitware.com/api/v1/app/5f4474d0e1d8c75dfc705482/extension

And entering on the extensions manager I see this:

[Qt] An OpenGL Core Profile was requested, but it is not supported on the current platform. Falling back to a non-Core profile. Note that this might cause rendering issues.

[FD] DevTools listening on ws://127.0.0.1:1337/devtools/browser/e3ac763f-981b-4330-8648-83f0249ecfe5

[Qt] Remote debugging server started successfully. Try pointing a Chromium-based browser to http://127.0.0.1:1337

[Qt] "https://extensions.slicer.org/js/chunk-vendors.faf86a0d.js" 7 "Uncaught (in promise) Error: Network Error"

[Qt] Uncaught (in promise) Error: Network Error

I have Slicer stable release 5.6.2

We are experiencing network issues for Kitware hosted servers, it should be back up now.
