I am having the problem that under Windows Windscribe takes really long to establish a connection. This is relatively new. It will take several minutes to connect while trying out different protcols as well. Since I am not getting any errors (it will eventually connect) I cannot get to the bottom of this. The problem does not exist on my Android devices in the same network. Under Ubuntu (Mint/Cinnamon) or using the Firefox plugin the connection is much faster as well. I am on version 2.4.10 Guinea Pig.
To clarify: This is about the time it takes to connect to the VPN, not the connection quality or bandwidth. While I am having occasional bandwidth issues the two do not seem to be related. I am getting slow speeds on Android but connecting is a matter of seconds. While on Windows both are slow.
