An unexpected disconnect occured

I also get the error "An unexpected disconnection occurred", sometimes unfrequently,
but now always in "Act 3 - The catacombs".
I've tried it 5 times. The first seconds the FPS is switching between 0 and 60 (VSync on), but when I try to move then I get kicked out to login screen.
But the connection (ping) is stable the whole seconds at ~50 ms.

My PC specs are:
Windows XP 32-bit
4 GB
Radeon HD 4850 (with latest AMD/ATI driver 13.1)

All game options are set to low (no shadows, no anti-aliasing, medium texture).

So I can't play on with my HC character, cause I've read that "The docks" also has this issue (until Act 3 Marketplace I've had no bigger problems).

Edit:
Now played Act 3 with another character and I was disconnected 5 times in the "Warehouse sewers" (nearly the same place).

So i found this post on one forums of a website. credits to the poster. His post is true and if any GGG mods, kindly take time to read this.

([Client] < - > [Server]
The client sends packets. The server requests more packets, the client responds with more packets, rinse and repeat. When your connection is lost, the server won't receive anything any more and after an x amount of time, it will consider you disconnected and will then log you out.

The "luck" factor is in the interval that's being used to consider you "disconnected".

Let's say a game checks every 1 second whether there is still a connection between the client and the server and if even 1 single request has a time-out, it will consider you disconnected. This has a few consequences:
- Any form of latency higher than 500ms could drop you immediately, often.
- Any spike in your connection, would drop you immediately.
- Extreme bandwidth abuse on both your network and the PoE network.

So normally, there's a few second interval before you actually get logged out.

It seems to me that PoE allows you to get logged out quite quickly, so you'll need to have a low ping to be able to play continuously, but your characters are safer, due to the fast response time on that time-out. So if you do get a DC, you will have about 3 to 5 (guestimate) seconds before the server recognizes this. If you die before the 5 seconds are over, you are actually dead. If you are at 1hp when the 5 seconds are over, your account is logged out and your character will still be alive. )

This post tell us something that may be connected to the desync problem POE is having. My assumption might be GGG programed the client to disconnect players once having high latency to prevent them from dying esp from hardcore league because of desync problems. I think its' like a protection for players and desync problems. Instead of watching our toons not moving or delayed movements or not hitting mobs because of spikes of latency or high latency resulting to death, client will disconnect itself. I hope they fixed this two, desync and disconnections. Because not every player have great internet connections or latency. Thanks in advance GGG.

HI, as of lately i been having the same unexpected disconnect issues. My Internet bandwith test says i have 20mb down and 10 up, on day break hours, 11 mb down and 5 mb up on peak time, usually in the afternoon.

My gaming system has 8GB mem, 64 bit win 7 OS, AMD FX6100 six core processor at 4.20GHz, corsair force gt sata disk device at 525 mb/s sequential read and 4k write, interface 6gbs per sec.

it has become so bad that i cant even play for more than 1 min anymore.

i tried putting my pc on a static ip channel and told the router to focus all its attention to it.

any suggestions?

im having the exact same issue. its very annoying and driving me into madness. if anyone gets this issue resolved please respond back into forums. Has any moderator even addressed this issue yet? I would like to know someone is working on this issue. There are so many forum threads right now about this issue. I am glad someone else posted on the forums about this issue. Fix yo shit GGG. :]
