[CRASH] Can't load into games because client thinks I have disconnected when internet is fine

Every few games or so, at a seemingly random interval, I am unable to connect to the game. I will load to 100%, then I will get the message "You have disconnected. Please check your internet connection and try again" even though my internet works fine. I have tried restarting computer, client, and internet, but whenever I try to (re)connect to the game I get the error message. Not sure what screenshots, logs, or further information would be helpful, so let me know if I can help in fixing this in any other way.
