client disconnections over slow VPN

[Neale]

We tested Servoy client over a slow VPN connection (OpenVPN over a modem link; routed IP tunnel) and found it to persistently suffer disconnections ("You are disconnected from the server.. Trying to reconnect").

The disconnection could be provoked by navigating to another recford in teh foundset (i.e. manipulating the slider on the controller).

Any ideas on where to start diagnosing this one?

Thanks,

If you have something in the network with cancels idle connections, but have a full access (no firewall blocking IP ports) you migth be better of with 2way sockets(this tries to keep connection open over firewalls) disabled in client properties panel.

Hmmm... there "shouldn't" be any issue with "something in the network with cancels idle connections" - there shouldn't be anything in the middle which is maintaining any notion of connection state. These disconnections are very frequent, as in *every* time we try to navigate from one record to another (FWIW, yes there are many related records) - so I'm pretty sure it's not an idle timer expiring.

We'll try disabling the two-way sockets as there shouldn't be any NAT/FW problems between the client and server (at least none that should be relevant to this).

Thanks,
Neale.

With the two-way sockets disabled the disconnections have vanished
