Installed and configured hass.io on rpi2 but changed ip of rpi2

I Installed and configured hass.io on rpi2 but changed ip of rpi2 because i moved it to another network. I can log into my home assistant front end and see things working, but configurator doesnt open, I get “took too long to respond” message and sad face file icon when clicking on Configurator on the left side panel. How do I fix this?

I already went into the configuration.yaml file via ssh and changed its host ip to the right ip. But I now get policy not fulfilled

Please delete…i fixed it, I had changed the allowed networks IP instead of the host ip.
