The backend does need to use SSL (HTTPS) if you plan on accessing it from a different machine. However, it is possible to run both the frontend & backend on HTTP, provided that you only use localhost URLs & you only access the site from the same machine where it is running (as this is a normal development setup).
It's unclear from the errors you shared whether you are attempting to access the site from the same machine it's running on, or not. The basic issue though seems to imply that the UI is not running at all (if you don't even see a loading screen or a blank screen or anything, that means the UI is not running at all). This would likely imply that something is incorrect in your PM2 setup or the UI configuration (config.*.yml). You could try running the UI temporarily via "yarn start" just to see if it starts up properly that way. If it does, then your PM2 configuration may require updates. If it does not, then it's more likely your config.*.yml needs fixes (and you may see some more descriptive error messages) Tim On Friday, September 2, 2022 at 3:14:07 AM UTC-5 [email protected] wrote: > Your backend must use ssl...
