Connection failed.
Network connection shutting down due to read error.

This happens -completely- randomly, and happens when trying to connect to some games(but cannot tell, because the BYOND box just closes and gives no display message what so ever, creating the illusion that you're 'router' banned.)
Numbered Steps to Reproduce Problem:
It happens completely random, or by trying to log onto a game.

Expected Results:
To be able to connect and play.
Actual Results:
Does the problem occur:
Every time? Or how often? Random.
In other games? Yes.
In other user accounts? Yes.
On other computers? Yes.

When does the problem NOT occur?
Did the problem NOT occur in any earlier versions? If so, what was the last version that worked? (Visit to download old versions for testing.)
Really havent had this problem much before the last couple of updates.

Note: This has been happening to other people as well too.
There is no way to verify this issue, but the networking code has not changed significantly in quite some time. The most likely culprit is a problem on your network, either due to frequently dropped packets (to the point of messing up TCP/IP communication) or a bogus filter. Some users at universities have noticed problems with aggressive P2P filtering mistaking BYOND traffic for sharing traffic and hurting their connections. A wireless network with poor signal is also a likely cause of frequent network errors.
