Probably a network error, is the server down?: [object Object]

[ms t]

I try to use janus's demo page.and I get this error:

Probably a network error, is the server down?: [object Object]
I noticed the page get a url like this:
https://www.iocollege.com:8089/janus
In fact,this no programe listen to the port 8089. and I try to do like this:

cp /root/janus-gateway/conf/janus.transport.http.jcfg.sample /opt/janus/etc/janus/janus.transport.http.jcfg

nano /opt/janus/etc/janus/janus.transport.http.jcfg

general:
https = true
secure_port = 8089

admin:
admin_https = true

certificates:
cert_pem = "/opt/cert.pem"
cert_key = "/opt/pkey.pem"
`

so,maybe some error stop to configs to general /janus.transport.http.jcfg .my config and run like this:

./configure --prefix=/opt/janus --enable-websockets

/opt/janus/bin/janus

and get this:

I recommend you to disable https on janus then put janus behind of an nginx reverse proxy using configurations below. Let nginx handle SSL.

location /janus {
  proxy_pass http://127.0.0.1:8088/janus;
}

location /admin {
  proxy_pass http://127.0.0.1:7088/admin;
}

For websockets:

location /wsJanus {
  proxy_http_version 1.1;
  proxy_set_header Upgrade $http_upgrade;
  proxy_set_header Connection "upgrade";
  proxy_set_header Host $host;
  proxy_cache_bypass $http_upgrade;
  proxy_pass http://127.0.0.1:8188;
}
 
location /wsAdmin {
  proxy_http_version 1.1;
  proxy_set_header Upgrade $http_upgrade;
  proxy_set_header Connection "upgrade";
  proxy_set_header Host $host;
  proxy_cache_bypass $http_upgrade;
  proxy_pass http://127.0.0.1:7188;
}
