Hi,

I'm using a vpn profile with tap device which is working seamesly on a Raspberry PI 3B, but with VPN Client Pro it connects but it stucks on "Connecting: Wait TapEmulator".

On the openvpn server I can see the device is connected but I don't receive any traffic of other devices on the network.

Please, can you post the VPN log?

Here the steps to get the log:

• tap on VPN profile name

• tap on LOG tab

• tap on top right icon with 3 dots

• tap on "Export log"

Hi, there is the log dump.

Please, try to set the ip address manually.
