DSL connection doesn't work in Netrunner 16

When I’m trying to connect it tells “DSL connection deactivated”, “PPP failed”. (using pppoeconf connection worked). In rolling release it doesn’t works too.

What settings are you using in plasma-nm (Network Manager) DSL settings?

I only change fields login, password and service (pppoe). It doesn’t wok in another distros with Plasma 5, it worked not in every Plasma 4.
