Hello!
I know there are many articles addressing this already, but I haven’t found one to work yet so hoping someone can shed new light.

MM 2.7.0 on an RaspberryPi Zero W and chromium

MM was working after initial setup, I was tweaking modules just to get my initial layout all set (occasionally getting the “please use a config.js” message, fixing my js then it worked again…
So now the issue:
Twice now after pm2 restart mmrestart from just changing config.js I get the browser page that the Site can't be reached... localhost refused to connect

1st time it happened I started going back through the whole setup again doing npm install, etc and nothing worked. I was just about to burn the whole thing down when…
Finally after one more sudo reboot after no changes… it just worked.
This time, it’s not coming back yet.
