I had this prblem for months and months!! When I open Minecraft it says this on the Update Notes, "408 Request Time-out," and this,"Your browser didn't send a complete request in time."

Put the summary of the bug you're having here.
I start my Minecraft Launcher, then I see 408 Request Time-out on the Update Notes tab, then I press play, then I select Single player/Multiplayer, and in Single player, I start a world or previous one and it crashes every time, and when I click Join Game in Multiplayer, it crashes every time!
