other docker services arent reachable for some protocols

setup -
we have a setup on rancher using docker containers based on alpine image. (3.4)
having service A exposes HTTP/S endpoint and service B exposes HTTP/S endpoint.

symptom -
service A tries to reach service B via HTTP and succeeds.
service A tries to reach service B via HTTPS and fails,while a non docker host reaches service A and B via https,
nslookup from service A to service B produces
nslookup: can't resolve '(null)': Name does not resolve

Name: XXX.com
Address 1: 216.....
Address 2: 2607:...
telnet to service B from service A doesnt work, while telnet to service B from non docker host works.

workaround -
switched to busybox/ubuntu image everything works.

we came across this issue (
https://github.com/gliderlabs/docker-alpine/issues/8) and we thin its still not resolved on 3.4 even for musl 1.1.13 is installed (tried even 1.1.15 on alpine:edge)
