Rancher2.0 install 3-node-certificate.yml succesfull but error 404 when reaching website

System: 3 ubuntu servers version 16.04.3 LTS
Docker version: 1.13.1
rke install script.

Installation procedure: https://rancher.com/docs/rancher/v2.x/en/installation/server-installation/ha-server-install/
Installation was successful but I cannot reach the Rancher website.
The only change I made was using an ip address of the first server (1/3) as FQDN.

In the browser : http://172.17.101.70 result “default backend - 404”

Question:
cert.pem: <BASE64_CRT> # ssl cert for cattle server.
key.pem: <BASE64_KEY> # ssl key for cattle server.
cacerts.pem: <BASE64_CA> # CA cert used to sign cattle server cert and key

cacerts.pem? If you self-sign, what value do you need to fill in ?
I have a cert.pem and key.pem .

I tested the template 3-node-passthrough.yml and the website is also not reachable.
Maybe only reachable via a tunnel?

Hello,

By default “website” is exposed on only one host, have you try with others hosts ?

Yes, don’t work.
You need to define the server who shall make the connection with the website.
