with NetworkManager 1.36.2-1 i'm unable to connect to the internet through DSL/PPPoE with a username/password provided by the ISP
maybe it's related to this: #940 (closed)
I'm using Manjaro and a few persons were affected: https://forum.manjaro.org/t/my-internet-connection-is-no-longer-working/105523/2
the solution was to downgrade network manager to 1.34.0-1, and i also downgraded libnm, though I'm not sure the latter was necessary, but i followed someones advice over there.
