Ionic 4 web app (cordova browser) crashes or redirects to a different page when multiple user tries to access same login account at the same time

I’ve deployed www folder of cordova browser platform from ionic - 4 project to AWS , when multiple users tries to login and access capabilities in the same login account the data does not loads or application crashes or redirects to different pages, I’m not sure what’s happening here and how to fix this, tried to check on the internet if same issue persists with others but didn’t find anything, any help in this regard would be much appreciated. Thanks
