hap ac lite metrics stays inactive

Hi from zurich

hAP ac lite // 3.25.10.0 // attached via tunnel
location set // map visible
call inbound an outbound works perfect

problem:
1) "metrics" on status (internal services) doesn't change from grey to green, stays inactive
2) my hap is not not visible in https://worldmap.arednmesh.org/ even after days of waiting
3) Status-page not accessible from outside (but I can access everybody!)

Which configuration did I set wrong? Any idea?

Thanks an best 73 from switzerland!
