Hello,

Sorry for the late reply. This error is an everytime occurrence for the first day of 3v3, if you have it make sure to refresh your game (every member of the team) and if then it still gives this error please clear cache / flushdns.

1. Clear the game cache (cog icon in the top right > clear up system)

2. Flush the DNS cache (open 'command prompt' on the PC and type ipconfig /flushdns and hit enter)

3. Reboot the PC (to be extra sure, reboot the modem/router too)

You'll need to perform those steps in that order, no skipping or re-ordering.
