Battle .net proxy server dilemma -fix!?

All of a sudden, my is saying

Your connection will be run through a proxy server because of your network setup"

This is new.
Things seem to be hinky. I cant join or create games (that are seen by others).
I cant think of anything I've changed
What might be causing this?

Maybe you're running a VPN. has a low tolerance level with any type of slightly non-standard connection setup.

Mainly due to people running Bot's to mine for high level gear.

Maybe describe your network setup + someone will have a work around.

When did you notice the error start?  

Assume as you regularly play SC it's something new you've spotted quickly. Do you normally play on Battle.Net or on other servers?

Top reasons why you see:
"Due to your network configuration, your connection to other players must be routed via proxy server" on Battle.Net (your network connection has changed).

    Make sure IE hasn't decided it's Offline
    Open Internet Explorer
    Press Alt + F
    Uncheck "Work Offline"
    If that's already unchecked check your LAN settings as below:

    Press Windows Key + R.
    Type inetcpl.cpl into the Run window.
    Choose "Never dial a connection"
    Choose "LAN settings"
    Uncheck Use a proxy server (if checked)
    Choose "Automatically detect settings" (if Proxy Server above is already unchecked)

Any recent installation may have changed your networking settings (intentionally or maliciously)

Your ISP may unilaterally change your connection settings (throttling)
You may previously have had port forwarding (:6112) for Blizzard set up on your router and this has been reset (by you, remotely by your ISP or because of a fault).

Apparently common issue after an update. See the blue post in this. Also, try the US server
