[Mara2000]

Hi,

i have new Robustel router R3000-L3H. I can´t connect to the server. CA.crt, client.key and client.crt are sucefully uploaded to the router but in log i see these errors:

With insys router and same auth files i can connect to the server without errors.

Thank you for help.

The error is pretty clear though.
> Error opening 'Private Key' auth file: /etc/openvpn/Tunnel_1/keypass: No such file or directory (errno=2)

so there is a reference somewhere to that folder and file, and it doesn't exist there.

Any luck with this?
I found the following worked for this particualar error:
enter a dummy password into the password field in the vpn settings,
submit,
save and apply,
repeate the above steps but this time delete the password from the field

Hm from what I understand now is that this device calls OpenVPN and references a text file that contains credentials - regardless of the fact that the connection needs credentials or not. And if it doesn't, and you haven't given it any, then the credentials file is missing, and things break. That seems like a very poor design on the part of Robustel. I'd report that as a bug if I were you.
