New client no connection with openvpn server
Posted: Sun May 08, 2022 10:10 am
Hi,
currently I'm using a openvpn server 2.3.4. with a openvpn client 2.4.0 on the Cubietruck with Armbian Linux 4.19.62. Everything is working well. I would like to replace the Cubietruck with a Rasberry Pi 4. An openvpn 2.4.7 is running on the Rasberry Pi with rasberrypi 5.10.103. Unfortunately, I can't get a connection to the server with the files from the Cubietruck. Where is the issue? Is this a version conflict?
