Server pls. what is this

The message “Failed to connect to the server” appeared in the text chat. This means the game client was blocked from reaching the specific IP address of the game server your match takes place in. This is NOT a problem with the server itself but a connection problem between you and the server.

Unfortunately all disconnections and game crashes counts as leaving the match and will be penalized appropriately. The game server has no way to discern a legitimate disconnection or game crash from one that is forcefully caused by a dishonest player to bypass leaver penalties. You can learn about this policy here:

Play several matches in quick play to see if you have any additional connection problems (carefully watch for that error message; note that in quick play the queue does not cancel if you get that error). If you are still having problems consider checking out these starting steps first:

Otherwise, please post in the technical support forum and provide the results of a WinMTR test where players like myself or Blizzard Support Agents can lend a hand to troubleshoot your connection issues.
