Yep and my cronjob is set to three hours??? I have gone back to 3.12.0 and though it is not perfect, it is better than the current. When disconnecting with the new version, the disconnect message is different and cryptic, too. I don’t see where to report bugs on their site either. Where can the daemon logs be found?
Please follow-up and give your feedback on the wireguard-tools/systemd-resolved workaround, if you give it a try.
