We have near 50k mobile clients(> 80% is Android) which send requests to the server during 20-30minutes with expected rate 50-100requestssec.
The problem is that 25% of clients got errors like
- ConnectionTimeout
- No host resolved
We use Route 53 + ELB + nginx + haproxy.
Any changes like maxconnectionsworkersmaxfiles at nginxhaproxytcp do not get any result.
We try performance loading with rate 800secreq and any connection issues were. (but from one IP)
So how we can investigate where the problem?
Are there any logs I can check at ELBRoute53 with declined connections?
