Hello,

I have installed Pritunl, and the client and server are not communicating via OpenVPN it is just UDP packets. I although still can connect and access the internet, but there are no OpenVPN messages/packets being sent between the client nor the server. If anyone has a solution to this it would be greatly appreciated.

Regards,  
Sqldns

There is more information in the [**client debugging**](https://docs.pritunl.com/docs/debugging-client) documentation on fixing connection issues. Try using TCP and setting the _Connection MTU_ to 1300.

Also the [**OpenVPN update**](https://docs.pritunl.com/docs/openvpn-update) documentation has information on updating the OpenVPN package on the server. This is often needed to fix compatibility issues with different versions on the client.

Hello,

This not a connection issue. The server and client are both sending UDP packets and the connection is fine rather they are not communicating via OpenVPN. As OpenVPN data is not being sent over UDP just UDP packets are being exchanged between the client and the server.

Check the [**connection fix**](https://docs.pritunl.com/docs/rhel-connection-fix) documentation. Try pinging the virtual IP of the server.
