Project page using AR.js sticks showing Page loading message

I have created a project using AR.js A-frame.
It takes camera input and do Augmented reality using NFT marker.
When I load the page, it shows camera live feed in background (dimmed) and some error msg “Page loading please wait”.
Due to this it’s not detecting the marker image.
I have only 1 camera in PC and using chrome.

Are you using Fastify/Express?

If yes, did you tell your code to send the client your home page?
