Login attempt failed Configurator on HASS Restart

Hey folks, I’ve searched and found a few posts on this but haven’t found an answer that has worked.
I access configurator from another machine. I use Configurator to “Restart HASS” I get a notification in Home Assistant:
Login attempt or request with invalid authentication from

If I add this to configuration.yaml, I get an error and Home Assistant won’t start:

    - type: trusted_networks

Error at startup: Invalid configuration for auth provider trusted_networks: not a valid value @ data[‘trusted_networks’][0]. Got ‘’

I’ve also tried playing with the configurator.py file and adjusting:
USERNAME = xxxxx
PASSWORD = xxxxx
Do these need to be in quotes or anything?

Thanks in advance!
