I registered on behalf of a friend of mine. Whenever we play online, he would get constantly booted out of the game and receive error codes. At which the 0x20010006 would be the most common one.
I believe the longest period of time we could play together - without getting any error’s - would be two hours. As of late, the game has been unplayable for him with errors occuring every 10 - 15 minutes. We’ve tried installing DMZ, forwarding ports and check his router’ firmware; unfortunately nothing of the above helped.
I’m a little frustrated about the fact R* hasn’t announced some sort of public statement about the matter. RDR2 is the only game that tends to give such errors.
