I'm assuming it was working for you before with an earlier version of Ubuntu, if so, the bug is probably NetworkManager 1.36 introducing a spurious route and in some cases spurious IP address, see later messages in the upstream bug report:
- https://gitlab.freedesktop.org/NetworkManager/NetworkManager/-/issues/946
Otherwise, I would need to see the log output with:
sudo journalctl --no-hostname _SYSTEMD_UNIT=NetworkManager.service + SYSLOG_IDENTIFIER=pppd
change any IP address to anonymise it if you wish.
I'll assume you were experiencing the aforementioned upstream NetworkManager 1.36 bug with spurious route and/or spurious IP address.
I'll close this issue as there is not much I can do, they need to fix the upstream NetworkManager 1.36 bug.
