Don't Starve keeps crashing

Hello :) 

I can play for like 5 minutes max untill the "you have lost connection to the server" message appears and the game crashes... sometimes it happens right after I start the game, sometimes it takes more time, but I couldn't play more than an our for the past couple of months.

Already tried all the troubleshot steps and none of it seems to be working... :(
