Create a notepad file and save it as regions.xml
Inside the file add these parameters
<regions>
<region displayname="AUTHENTICATION_SG_REGION" hostname="sg"
allowedProductLocales="all" localesThatDefaultToThisRegion="enSG"/>
<region displayname="AUTHENTICATION_US_REGION" hostname="us"
allowedProductLocales="all" localesThatDefaultToThisRegion="enUS"/>
<region displayname="AUTHENTICATION_EU_REGION" hostname="eu"
allowedProductLocales="all" localesThatDefaultToThisRegion="enGB"/>
<region displayname="AUTHENTICATION_KR_REGION" hostname="kr"
allowedProductLocales="all" localesThatDefaultToThisRegion="koKR"/>
<region displayname="AUTHENTICATION_SEA_REGION" hostname="sea"
allowedProductLocales="all" localesThatDefaultToThisRegion="enSEA"/>
</regions>
Save to starcraft 2 installation folder
