Openvpn with 3CX PBX

[Vrp]

Hello, I'm installing an Openvpn client on a Debian machine with the 3CX PBX installed. After installation, the web server started sending me a 502 error and accessing it via browser does not work anymore. Can someone help me?

Yes, uninstall the OpenVPN client.

Is there no way to use a VPN on the PBX?

Hello Vrp,

Please check here https://www.3cx.com/blog/docs/network-configurations-supported-3cx-phone-system/ and may it help you.
kindly note 3CX strongly recommended to keep the machine instance dedicated and do not install other software.
