@tom: the first place I'd look is your ec2 security groups

bhagany: localhost should works anyway

Today I have weird issue, my app was running but health-check was unhealthy

mccraigmccraig10:09:30

@tom: localhost may not work if your app is only listening on a single network interface, e.g. eth0 or if your app is running in a container. investigate which processes are listening on which ports with "sudo lsof -i"

bhagany11:09:52

@lowl4tency: you're right, of course

jaen11:09:06

Funny thing is how redirects (say, from http to https) are considered an unhealthy app by the ELB health check.

lowl4tency11:09:40

First, I checked port is listened, second try to connect via telnet. third take a look on log-file

lowl4tency11:09:58

jaen: it's not funny, it's hurt

jaen11:09:37

Well, yeah, "funny"

lowl4tency11:09:47

I've got ELB and S3 bucket with maintenance page, when ELB is not available I've got ssl error instead the page 😞

jaen11:09:10

I had to to special it so that ELB's user agent doesn't get the redirect

jaen11:09:28

Well, that's sad
