Error 34200, please help!

I cant log in to public serve and error code 34200 since yesterday. Anyone can help?
Please advice

disable your Firewall and make an update.
There was a little Patch, now its working for me.
Somehow my Firewall blocked this Patch

Hey Real,

Along with the advice that Knarz33 gave you, try out the following too:

  • Log out of the Blizzard Battle.net Desktop Application
  • Switch regions to a different region than the one you usually log in from (if you play in Europe, switch to the Americas)
  • Log back in and start Diablo III
  • Open the Community tab
  • Quit Diablo III and log out of the Blizzard Battle.net Desktop Application again
  • Swap back to your normal Battle.net region and retest.

Hopefully that will help!

If you mean “Public Test Realm”, you won’t able to login because there is no public test right now. The server is closed until next public test which has no schedule yet.
