piHole webinterface not reachable

Hi there,

i just installed a Raspberry pi 3 b+ with piHole in the Balena Cloud. I followed this tutorial:

Sadly, i am not able to access the Webinterface of the piHole Service.

This site can’t be reached

192.168.188.114 refused to connect.

Try:

ERR_CONNECTION_REFUSED

The Pihole seems to work in general.
Any Ideas?

Thanks and best regards
