Runs well locally, but not compatible when hosted online (Google App Engine)

Hello!

So I have a website that uses the following APIs:
POST /privateapi/auth/post/getToken
/commonapi/search?searchVal={SearchText}&returnGeom={Y/N}&getAddrDetails={Y/N}&pageNum={PageNumber}
/privateapi/routingsvc/route?start={start}&end={end}&routeType={routeType}&token={token}

It was working perfectly on my website for 2 months, until around 26 August 2020. I did not edit my code or change anything to it, it just suddenly started to have the following problems. After that day, my website faced the following issues:

  • OneMap apis were taking more than 3 minutes per request (usually less than 1 sec).
  • The api calls kept rerunning.

I tried running locally, it still works perfectly fine.

Is anyone facing this issue too? :frowning:
Or does anyone know how to resolve this?

Thank you!
