Since yesterday, this error started popping up when using the command sandy.get_endf6_file.
This appears when sandy tries to connect to the IAEA nds website to collect nuclear data.

I can only assume that yesterday the IAEA NDS changed some server security features to block this kind of actions.

A solution to get around this was found in here and here.

This is implemented in the latest push to branch v1.1: c52f105.
This issue will probably speed up the release of branch v1.1 (tag + merge back into develop) to August.

I didn't check, but I assume that any sandy branch/version before c52f105 will no more be able to fetch remote data, and can only work with local files.
In case you don't know how to do it...instead of using sandy.get_endf6_file, just do the following:

• download the ND file locally to your computer (name is FILE)
• read it as a sandy.Endf6 instance with sandy.Endf6.from_file(FILE)

Hopefully commit c52f105 fixes the problem once and for all, although I wonder what will happen if the IAEA NDS find a way to completely block this sort of access...
