There is no cure. Just venting. I'm fed up.
Have played the game without issues before. Decided to give it a go again and installed it about a week ago. However.
It keeps disconnecting and showing the same error code over and over again. I've searched the forums, tips and everything I've managed to find about the situation, but so far nothing has worked. And I am 99% sure the fault does not lie in my end. Especially since the internet connection has been stable and everything else has worked without zero connectivity issues.
Doing the story missions has become impossible (currently stuck at the Retribution), since I've not managed to beat the timeframe when decides to disconnect. And though logging back in only takes a second, one is instantly thrown out of the story instance. Why has there not been set a minute or so for a buffer zone to avoid needless restarts is beyond me.
So. I guess my choice is, for the moment, just to check back in for about a month or so and see if the issue has magically fixed itself or not. At least that seems to be the only "fix" that is at least somewhat popular. But I am not sure if I can be bothered then anymore.
TLDR: If you've got the same error, just give up.
