I need help with this error log

[drksbr]

I have a connection profile that works perfectly if I issue the command:

openvpn --config PROFILE.ovpn

however, when using the desktop example it returns the following LOG and does not complete the connection:

Openvpn log >> Creds: UsernameEmpty/PasswordEmpty

eg session := openvpn3.NewSession(config, openvpn3.UserCredentials{ Username: "user", Password: "pass", }, &loggingCallbacks{})

It is still the same even now. We don't necessarily need to send the username and password.

This is the error I am seeing on the server:

however when I use it with the openvpn client, it just works

@antonyr I have same issue, do you have solve it?

[antonyr]

Hi @nikohpng nope, I couldn't resolve it and I had to use a different software to get around it.

[nikohpng]

@antonyr do you find other like go-openvpn？I don't want to use cmd to control openvpn in golang. can you share it if you find it. maybe I need to fix it if can't find library.

[antonyr]

It was not a go based one. It is entirely a different one for windows.

[nikohpng]

I update openvpn library to solve it. maybe the library is oldest. If someone need it, please contact me.

Hi, I have a problem with building an OpenVPN app for windows, can you share it with me, maybe it can help to solve the problem. Thanks!
