Can't download the game (Red Dead Redemption 2)

Good afternoon. Yesterday got the key for RDR2 on PC installed Rockstar Games Launcher, registered the purchase, indicated in the launcher way to install the game and put in the fix...it took 40 minutes, I downloaded 6 GB and I have lost the connection to the server...the Internet is working, other launchers too...and this not...what to do? has anyone faced such a problem?
