172.30 ip range


It’s the 2nd time in a few days I get some stange message from an internal ip address which isn’t mine.
it’s the 172.30 range.
I use 192 for local and 10.x for vpn, never do I use 172.30
is HA using this somehow interally.

the messages I get are:

and in the observer

22-02-15 21:47:50 ERROR (MainThread) [supervisor.api.ingress] Ingress error: Cannot connect to host ssl:default [Connect call failed (‘’, 62661)]
22-02-15 22:00:27 ERROR (MainThread) [supervisor.homeassistant.api] Error on call
22-02-15 22:00:27 WARNING (MainThread) [supervisor.misc.tasks] Watchdog miss API response

is this something HA uses internally? or should I be worried someone has compromised my system?
for as far as I know this is a private ip range so it can’t come from outside.

Yes it is the internal Docker network.
