PPPoE connection error

[alevan]

Hello.

I'm trying to get OPNSense working with my ISP (RDS & RCS from Romania).

But I get these errors on the Point-to-Point Interface after connecting, and the connection is dropped afterward:

1. PPPoE: can't connect "[91]:"->"mpd95443-0" and "[9c]:"->"left": No such file or directory
2. IFACE: Adding IPv4 address to pppoe0 failed: File exists

This is the whole log for this connection:

Does anybody have some guidance what can I do?

The device is a freshly installed Intel N100 mini PC with 4xIntel I226-V, so theoretically it should not be the network interface.
