OpenVPN Support Forum

Ok, I have a script for both connect and disconnect which set is_user_online to =1 if he gets connected/connecting and disconnect to set is_user_online to =0 after he disconnects so he can connect again so the problem is when he get reconnects on TCP his is_user_online is to =1 making him can't connect or get an AUTH_FAILED error while on UDP i believe if explicit-exit-notify is included this make user when reconnects then he push to click the disconnect script.

Is there any recommendations for TCP connection?

UDP is a connectionless protocol ..
--explicit-exit-notify is used to notify the server that the client is disconnecting from the VPN.

TCP is a Connection-Oriented protocol ..
There is no requirement for --explicit-exit-notify as the TCP protocol handles the connection state.

This suggests there is an error in your script.
