Can't get stable service

[dvidlui]

Hi,

I am using this open source for dynamo geo query.
And I am making request from iOS mobile application.
But I can't get stable service. I am using t2.small instance type.
By the way, even though I sent request less than 10 per minute, I have got a lot of timeout errors as the response.
And, since I have got issues, even though I did not send any request, its instance health is changing "Ok" -> "Warning" or "Degraded"

I'd like you to let me know what the problem is.
Thanks
