Cannot download SAMD Boards Package

Hi!

I'm not able to download the SAMD Boards Package any more.

I did uninstall Arduino several times and also tried an old version.
However it worked in the past.

Using the current version of Arduino (1.8.5) it says (or hangs up):

Fehler beim Herunterladen von http://downloads.arduino.cc/tools/openocd-0.9.0-arduino6-static-i686-w64-mingw32.zip

Any idea what I could do to solve this?

Thanks in advance and Best regards

Try it again. 503 error is probably just a temporary server issue.

I'm facing this issue since weeks. Tried it a lot of times.... No success....

The interesting thing is:
Downloading the file http://downloads.arduino.cc/tools/openocd-0.9.0-arduino6-static-i686-w64-mingw32.zip via my Browser (Chrome) is working properly...

Problem finally solved - The reason was a (company) firewall setting...
