North American Server Issues for SEA players

If you are having any of the following issues:

• Patcher Crashing
• Unable to download authentication module
• Quick match screen is blank
• Arcade Games being listed as "…" and never loading
• CLIENTSIDECACHE_READ_HTTP_FILE_NOT_FOUND Error when joining custom games

Then you may be encountering some of the issues affecting the North American server that seem to be unique to SEA license holders.

Blizzard have recommended the following as a temporary work around:

DNS settings are specified in the TCP/IP Properties window for the selected network connection.

Example: Changing DNS server settings on Microsoft Windows 7

• Go [to] the Control Panel.
• Click Network and Internet, then Network and Sharing Center, and click Change adapter settings.
• Select the connection for which you want to configure Google Public DNS. For example:
  • To change the settings for an Ethernet connection, right-click Local Area Connection, and click Properties.
  • To change the settings for a Wireless connection, right-click Wireless Network Connection, and click Properties.

If you are prompted for an administrator password or confirmation, type the password or provide confirmation.

• Select the Networking tab. Under This connection uses the following items, select Internet Protocol Version 4 (TCP/IPv4) or Internet Protocol Version 6 (TCP/IPv6) and then click Properties.
• Click Advanced and select the DNS tab. If there are any DNS server IP addresses listed there, write them down for future reference, and remove them from this window.
• Click OK.
• Select Use the following DNS server addresses. If there are any IP addresses listed in the Preferred DNS server or Alternate DNS server, write them down for future reference.
• Replace those addresses with the IP addresses of the Google DNS servers:
• For IPv4: 8.8.8.8 and/or 8.8.4.4.
• For IPv6: 2001:4860:4860::8888 and/or 2001:4860:4860::8844
  
• Restart the connection you selected [from above].

If problems persist, make sure to follow the suggestions in this thread and provide the information requested so that they can track down the issue.

(xpaperclip Edit: )
Alternatively, if you don't want to/can't change your DNS settings, add

117.121.253.106   us.depot.battle.net

to your c:\windows\system32\drivers\etc\hosts file. (Or whatever IP you get when you ping sg.depot.battle.net)
