Error connecting to an unknown IP

I have noticed a repeated error logged from the supervisor

 ERROR (MainThread) [supervisor.api.ingress] Ingress error: Cannot connect to host 172.30.32.1:64929 ssl:default [Connect call failed ('172.30.32.1', 64929)]

Does anyone know who this IP belong to that the supervisor want’s to connect to all the time?

It is in the ip address range for the internal Docker network.

Home assistant is failing to connect to one of your containers.

This has nothing to do with external devices. As stated in my post above the address is for one of the internal Docker containers that Home Assistant uses.
