Suddenly get DCed. and cant Log in back. LE-52

so ive been playing this game since the launch of 1.0 for 300+ hrs without having disconnected.
now i keep getting error LE-52.
i tried to restart my steam. tried like 3-5x log in. im able to go back. but after 10-15min. i get dced again and getting the same error LE-52. and it keeps happening
now its very frustrating.

saying “check my internet connection” which is perfectly fine…
