Technical Unnable to connect (DNS)

[garmin]

Hi, everything worked well for years utill today. I cant connect to any warmane realm (or any other wow server). Its "connecting" for 15 seconds and than it shows "unable to connect, please try again later". I had DNS set to automatically use default gate, than i changed to google dns (8.8.8.8, 8.8.4.4.) without any change...than i tried to use "set realmlist 188.138.40.87" and it connects to show me the tab with all warmane wotlk-realms, but when i choose one i cant connect to it ("trying to connect" than it fails).

-Realmlist file:
1) "set realmlist logon.warmane.com" - doesnt work at all
2) "set realmlist 188.138.40.87" - works like i said

-Config file looks normal:
SET locale "enUS"
SET hwDetect "0"
SET gxResolution "1920x1080"
SET gxMultisampleQuality "0.000000"
SET videoOptionsVersion "3"

SET Sound_VoiceChatInputDriverName "System Default"
SET Sound_VoiceChatOutputDriverName "System Default"
SET watchFrameWidth "1"
SET gxRefresh "50"

Uaaahhh, problem solved, finally.....this helps me:

Run CMD as administrator and type "ipconfig /release" and wait few seconds, than type "ipconfig /renew" and wait again and finally type "ipconfig /flushdns" and repair is over, restart WoW and play :)
