[Vuejs]-Nuxt / VueJS Page Rendering Fine on Desktop & WiFi-connected Mobile Devices, but not on devices on 4G/5G. Any idea how to fix this?

Thank you @Michal Levý for pointing out that none of the images were loading for him on a desktop browser.

I feel stupid.

Fixed some issues with the Nginx reverse proxy config, some middleware configs here and there, and set ENV to production, and somewhere along the way things got fixed. That was a headache.
