Hi everyone,
many of you had the same problem as i did >>"Could not log in to World of Warcraft at this time. Please try again later"<<
What i do to fix it is disabling firewall and via /cmd making Flush your DNS and IP. Open Command Prompt, type out each of these commands, and then hit enter, one at a time: ipconfig /release, ipconfig /renew, then ipconfig /flushdns. Once you’re finished, attempt another connection. It is possbile u need to repeat it multipletimes to make it work. Give me some feedback if it works fo you so. I hope it will help you guys :cheers:
