I don't have the problem.
I rebooted auth server, you still get this error?
You can access to this address ? https://auth.wrobot.eu/o
You can also try to use google or cloudflare DNS (and restard computer).
To be sure that it isn't the cause of the problem please disable this plugin. You can also try to download Wow client in another website (to be sure that it is not modified).
Hello,
You use modified wow client? You have try to disable wow addons and wrobot plugins? To disable your antivirus? Check if required softwares are installed?
Hello,
Disable all Wow addons, all WRobot plugins and share your log file please ( https://wrobot.eu/forums/topic/1779-how-to-post-your-log-file-with-your-topic/ ).
