lost connection to server

Hi,

The issue is the following: Sometime, I try to connect to the vassal server, and I can’t. After a few seconds, I’ve got the following message: “lost connection to server”.
It happens randomly. Sometime, it happens when I am playing with an other player. When I reboot my box, it looks to work better but not always.
It looks like it comes from my Internet Provider. for instance, connections to mail server fail when this problem occurs. But Internet accesses works well.
I tried to modify the firewall set-up: no effect.
tracert find a route to the vassal server.
ping works well as well.
here are the features of my PC set up.

  • Model: PC LENOVO T420
  • Operating System windows: 10.0.14393
  • CPU IntelCore: i5 2,5 GHz
  • Memory: 4Go
  • Video Card: Intel HD graphics 3000
  • Vassal version: 3.2.16
  • Java version: 1.8.0_77
  • Vassal module: VASL 6.3.3

Best regards,
Phil
