Wireguard stays in failed state if DNS-Request fails

[fleinze]

PROBLEM DESCRIPTION

When wireguard is started (manually or automatically at startup) a dns-request is sent if the endpoint address requires it. If this dns-request fails or times out wireguard stays in a failed state until it is manually restarted with backlog wgstop;wgconnect
Other Services like NTP or MQTT retry after failed DNS Requests.
It would be great to add dns retries to wireguard as it would make it more resilient.

TO REPRODUCE

Steps to reproduce the behavior:

EXPECTED BEHAVIOUR

Wireguard should automatically wait for a certain amount of time (e.g. 30s) restart after a failed DNS request.

You have probably issues since trying to use Initialized 'tasmota-zbtest.local' Using mDNS extension .local is not supported with Tasmota. It does not work and creates issues.
