Subscribing to pushnotifications is failing on Galaxy S10 and 10+ on Android 9

I am using browserstack which is apparently testing on real devices.
Using this site https://gauntface.github.io/simple-push-demo/
Gives the error
Ooops a Problem Occurred
abortError: Regsitration failed - push service error

This happens on Chrome and Firefox
The device is Android Version 9

One UI version 1.1(I don’t even know what this is)

I’m also facing same problem on many apps and sites from last week. Please help me to resolve this issue.
Thanks…
