Hi everyone!
I'm trying to update Recalbox with no lucky, always says "no updates available" o "no network connection" (network it's ok).
Via SSH I execute recalbox-upgrade.sh and...

Resolving archive.recalbox.com... 51.15.201.222, 51.15.208.162, 163.172.157.49, ...

HTTP request sent, awaiting response... 404 Not Found
2017-12-07 00:24:04 ERROR 404: Not Found.

I think 4.0 version it's too old and scripts aren't updated, so Recalbox can't find upgrade sources.
Hope anyone can help with this.
Regards =^)
