I’m using the 750S (Slate, 3.009) and try to establish a VPN-connection to my Raspberry Pi running an OpenVPN-server. The Raspberry works well with other VPN-clients.
First problem I had to solve was the askpass, which I had to add to the ovpn-file I got from my Raspberry Pi because at the Slate I had no chance to enter the password I had chosen. Solved.
Now I get the following error messages:
Incoming Control Channel Encryption: Using 256 bit message hash 'SHA256' for HMAC authentication TCP/UDP: Preserving recently used remote address: [AF_INET6]2003:d7:b7ff:22df:3631:c4ff:fe49:ef07:11941 Socket Buffers: R=[163840->163840] S=[163840->163840] UDP link local: (not bound) UDP link remote: [AF_INET6]2003:d7:b7ff:22df:3631:c4ff:fe49:ef07:11941

Do you please have an idea what I have to do now?
