Can't seem to connect my Traefik instance to Pilot

I got an email saying

Traefik Pilot has not been reached by any proxy of those instances recently (Token name / Last instance heartbeat):

* Instance – Mar 2, 2022: map[data:map[lastHeartbeatByTokenValue:map[Instance – Mar 2, 2022:<nil>]] sgParameters:map[templateID:d-xxx templateName:Heartbeat versionID:xxx]]

Not sure where to start debugging the issue, I don't have any firewall so I'm puzzled about this.

Hello @Luckymethod

Do you still experience that issue? Can you please confirm that?

Thank you,
