I get this error very frequentely: Frame cannot be read from the data source

[CornCakePie]

Several times a day if I have to close and reopen my application, I get this error and after that I have to completely restart my application in order to connect back in:

8/20/2014 1:18:09 PM|Fatal|WebSocket.processException|WebSocketSharp.WebSocketException: The header part of a frame cannot be read from the data source.

if I try to reconnect I get:

And thanks a lot for the awesome project.

Plz describe your environment more (e.g. network environment, etc).

Those errors occur when the connection closes suddenly.

[CornCakePie]

Modem directly connect to internet, I have also left a monitor running pinging/checking the route to a few domains to make sure it was not a network/internet issue.

And the socket I am connected to sends message on 30 seconds interval when idle so I can clearly see it just crashes out of nowhere does not seem to be a issue with the internet at all.

It also doesn't let me reconnect as I described on the other issue at:
#72

I've placed them separately as I don't know if there is a connection between the 2.

same error,help!!!

[sta]

@leixl Could you please describe your situation (and environment) more?

I'm getting this issue as well (On the client), but it seems to be occurring somewhat randomly with basic event-driven usage.

I get this error on websocket client side. It happens from time to time (not often).
I found that the method which should receive 2-byte header, actualy receives 0 bytes...

[ladytellur]

Such error may happen for example if ping request was sent to websocket-sharp client too fast (immediately after connection)
So if server side is in your competence, timeout on sending might help

Hi together!

I had the same problem and took a closer look at the infrastructure I'm using.
Turned out that I had a nginx tcp proxy in-between which default timeout is 60 s.
So, when there were few events for some time, the connection died with this message and I also wasn't able to reconnect.

Got the inspiration from here: #41
