Is the janus cloud that I have composed in the right form?

[hunyoungkim]

Hi
I have configured the janus cloud with the structure below.
Is it correct to make this structure?

tomcat -> videoroom.js & janus.js -> janus-proxy -> janus server & janus-sentinel

I had to use spring and janus server so I configured it like this.
tomcat -> videoroom.js & janus.js

tomcat -> videoroom.js & janus.js uses STS of WINDOWS,
janus-proxy -> janus server & janus-sentinel is running using WSL's Ubuntu.

Now janus cloud is not working due to SSL related issues.

Problems encountered:
NGROK :
HTTP Requests
------------- OPTIONS / 500 Internal Server Error
OPTIONS / 500 Internal Server Error
OPTIONS / 500 Internal Server Error
GET / 500 Internal Server Error
OPTIONS / 500 Internal Server Error

janus-proxy :
ws4py.exc.HandshakeError: HTTP method must be a GET
ws4py.exc.HandshakeError: Header HTTP_UPGRADE is not defined

I am using NGROK to access janus-proxy with certificate issue.

Do you have any information that might help me?
