Rancher Server + ELB very slow (solved)

Hi everyone,

I have a Rancher Server enabled on HA in AWS environment where there is one ELB in front of two ec2 instance. The problem is that the access from the ELB to my UI is extremely slow in relation to the direct connection of ec2.

ELB: Browser response in 6s
ec2 (public IP): Browser response in 700ms

Anyone can helpme?

I solved this problem changing the ELB listener to TCP instead of HTTP.
