Hi Team,

I have configured nginx setup like below

Nginx running as front end reverse proxy and routing live traffic to couple of upstream servers onprem and aws ( Refer attached file site.conf ). Here we trying to mirror the original On-Prem hosted application traffic to AWS hosted application which we using it as pre-production testing before completely migrate application to AWS cloud.

We noticed below things,
1.All original live traffic routed to onprem upstream server which is running on localhost:10200
2.We see few request failed with connection timeout while mirroring to aws upstream server which is running in AWS cloud

I am getting below error in nginx error log
connect() failed (110: Connection timed out) while connecting to upstream

Kindly help me to solve this.
