pic not showing in app after migrating server.

Hi, got an issue with my frontend in app. Image is all set on our laravel system but in the app none of the pic showed up. we dont change any api files. supposedly if the pic load in our system, in the app it show up as well...

both our app having the same problem, pic not loading in app..

what it could be the error? how can i debug the error coz we  just migrating server (changed to new ip address).

Permissions? Are you seeing 404 errors on the frontend?

no...nothing appeared in apps....all the pic not showing in our apps
