Somehow SDIO can not connect to the internet. Windows firewall is allowed. The computer is in a corporate domainnetwork with a proxy. Does SDIO contact some shady website (torrent) that is possibly blocked by the proxy-people?
If the network crew has blocked torrents, they’ll know how to unblock it. You can adjust the port used on the Options dialog, Updates page. Go there to see what port it’s using and change it if you need to. I’ve heard of some people using port 80 in extreme circumstances.
You can also switch off automatic updates from here.
If they don’t want to help out, trying to circumvent the restrictions won’t end well. You might be better off keeping a portable drive and updating it offsite once a month.
