v15_beta - session-start fails to connect #61

Closed HerissonMan-TMP closed 2 years ago

HerissonMan-TMP commented 3 years ago

Hello,

I installed OpenVPN Access Server on a Azure Virtual Machine, and when I attempt to run the command "openvpn3 session-start --config /home/kali/Downloads/client.ovpn", I have to enter the username and password. Few seconds after entering the password and pressing Enter, I get the following error:

session-start: ERROR Failed to connect: Connection, Client reconnect

Here are the logs

Waiting for session to start ... Done

I search a lot of hours on the internet how to resolve that problem, but I found nothing, so this message is like my last hope :(

Could someone please tell how can this problem be fixed?

Thanks in advance

You are going into a connection-retry loop for a bit, as it cannot access the VPN server.

Could it be a firewall issue on your AS server or hosting facilities?

Closing as no further feedback has been provided. Most likely the client could not access the server, hence it goes into a connection retry loop.
