There seems to be an issue where some people are facing a problem where when they upgrade then it's giving them errors on the dashboard such as "network error" or others, that relates to the fact that the frontend built files is unable to communicate with the PatchMon server.

This seems to be due to the frontend environment file containing a variable `VITE_API_URL`

Once you remove or comment this out and go back to the PatchMon installation directory where you're able to see both frontend &amp; backend directory then run `npm run build`

After this it should start working again.

As a rule of thumb if the `VITE_API_URL` is to be set then set it the same as your `CORS_ORIGIN`.

Ideally keep this unset and build the files.
