AWS deploy issue

Hello everyone
I have deployed on AWS server
the server ip is http://13.48.3.49/
I did below:
git clone from repo of jitsi-meet
npm install
npm install lib-jitsi-meet --force && make deploy-lib-jitsi-meet
make dev

and install nginx and proxy setting : listen : 80 and proxy : https://127.0.0.1:8080

so if i call server ip then runs well
but console there 's wds disconnected error occurs
plz help me
thanks

I think socket calls localhost:8080
but should call serverip
how to change this?
