Hey!
I recently (~2 weeks) started having trouble downloading from the nixos cache. Most of the downloads are failing with a SSL Connect error (35). After several fails, I am usually able to download the binaries.
While this is not a roadblock, this is pretty annoying.
For instance, when I try to build a derivation having a new dependency, it looks like this:

I did not experience this network error anywhere outside of the nixos cache.
Am I the only one experiencing this problem? Is there any way to get a more detailed diagnosis?
