Did you have this option checked in the WireGuard Config over PPPoE ? -- DNS Update: _x_ Continually Update DNS Endpoints for peers --
As long as the DNS A record did not change, the PPPoE connection could go down and return and all would be fine. Without the need for the "DNS Update" option to be checked. But, if the PPPoE connection was down, AND you restarted WireGuard, then the WG Endpoint would be unknown, and later if PPPoE returned, without the above option checked, the DNS endpoint would never be found. Understand, the cause of the above scenario is restarting WireGuard. If the only problem was the PPPoE connection was down, and it eventually returned, the WireGuard tunnel should come back as well without the need for the "DNS Update" option to be checked. But, if the WG DNS endpoint was some sort of dynamic DNS or could easily change, then the "DNS Update" option should be checked. Bottom line, if this ever happens again, first determine if the PPPoE connection under WireGuard is active and working before taking any actions.
