It is possible that you get disconnected from the server because the download speeds drop below minimum threshold the server is configured to allow. But why would download speed matter in preventing this error? The bigger buffer sped up the process and the errors stopped immediately, most likely because the overall download speeds increased. Using (FileStream content = File.Create(DownloadPath))ĬopyTo() method has a default buffer size of 81920. Fortinet Error Happened When Ing Ssl Vpn Client Plugins code#What helped was to change the code to: using (Stream remoteStream = await ()) While ((read = await remoteStream.ReadAsync(buffer, 0, buffer.Length)) != 0)Īwait content.WriteAsync(buffer, 0, read) Īfter some time I found out the culprit was the buffer size, which was too small and didn't play well with my weak Azure instance. Using (var content = File.Create(DownloadPath)) I was getting this exception when reading the HttpResponseMessage in a loop like this: using (var remoteStream = await ()) What do you reckon? It might be inconclusive I guess, but perhaps someone else has seen this kind of thing?įor anyone getting this exception while reading data from the stream, this may help. the code has a bug) and the 0#0 means that a packet of zero bytes is trying to be sent. The connection is still open, and a packet of zero bytes is being sent (i.e. The 0#0 simply means that nothing was sent because the socket was already closed. The connection is being closed, but data is then being written to the socket, thus creating the exception above. One of two possibilities is occurring, and I am not sure which, Verbose: 0 : Exiting Socket#30180123::Send() -> 0#0īased on other parts of the logging I have seen the fact that it says 0#0 means a packet of 0 bytes length is being sent.

What could the causes be? I can kind of guess a few causes, but also is there any way to add more into this code to work out what the cause could be? The connection is alive and well, and heaps of data is being transferred, but it then becomes disconnected out of nowhere. This happens with a socket connection between client and server. This Connect button works same as FortiClient SSLVPN (Which was installed with WebPortal) profile connection so after you fix your Fortissl adapter problem 'Connect' button will You are right new version has no bug same as all olds but all of version can be used with Fortinet Switch so if another IT Admin was installed switch with a diff version of FortiClient so all Win 8.I am working with a commercial application which is throwing a SocketException with the message,Īn existing connection was forcibly closed by the remote host ![]() Try to connect your VPN with FortiClient SSLVPN and probably it will work so after one more reboot you can enable plugin and using WebPortal 'Connect' button. ![]() Problem comes with PPPoP WAN Adapter can work with Fortissl adapter correctly after reboot please check your Fortissl adapter and disable your IE Fortinet plugin.
