At one point, I had OpenVPN up and running on my raspberry Pi. Connecting was painless -- I could use OpenVPN connect on my phone, and all was well. That is, until it wasn't. Something stopped working -- I'm not sure what. So I decided to start over. New download, new keys and self-signed cert. Things seem to be getting close, but I'm stuck on something with no connection to the VPN, with some errors in the log file. OpenVPNConnect app attempts to Connect, gets a SetTunnelSocket return 1 and ultimately a connection timeout. On the router, I've set up port forwarding -- I'm just not sure what to do with the "Operation not permitted".
Here's the openvpn log:
