No connection when using OpenVPN on router

I apparently configured correctly the OpenVPN Server on a Beryl AX AX3000 Wi-Fi 6 Router, but it doesn’t connect to VPN providers. When I use the VPN directly on the PC or Android tablet, the same providers connect (NordVPN and ExpressVPN). (I have no problems connecting to ExpressVPN with an ASUS router configured for this function.) When using the Beryl GL.iNet router, I keep getting an orange light and the message “connecting to the server”. The problem doesn’t occur when I use the Beryl router with the WireGuard protocol (with AZIREVPN servers). Is there anything I can do to get things running on the router?

Pls post the log.

The most popular reason is that you used the wrong username and password
