Connection lost

i was in competitive game when 1 player leave the game (leavers i hate leavers).
When the warning about leaving the game appear, “you will be penalized”. the game sent me to the login menu and it said “lost connection”

This took away points even though I reconnected as fast as I could because it was not my connection problem and I want to report it because it is not the first time it happens but if the first one in competitive

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:

Remember if you see the message, “Lost Connection to the Server” in the title screen or the message “Failed to Connect to Server” in red text in the text chat box, this means there is something that disrupted your connection to the game server and not a problem with the game server itself. There can be a variety of reasons this happens including those that don’t disconnect your computer from the Internet. There is great troubleshooting to start with that can most likely resolve most issues and I encourage you to check them out here:

As always if nothing in that guide works, please start a new post in the technical support forum saying you completed these steps and additional advice can be provided. Good luck!
