How to use HTTP connection?

[JJ_Lin]

For some reason. I'd like to use HTTP only for my MCU server. There are som configuration below according to doc.

portal/portal.toml

[portal]
keystorePath = "./cert/certificate.pfx"
# hostname = "" #default: ""
ip_address = "my public ip" #default: ""
# Port that the socket.io server listens at.
port = 8080 #default: 8080
ssl = false #default: true
force_tls_v12 = false #default: false, tls1 and tls1.1 will not be allowed if set to true
#The network inferface the socket.io will be bound to in case portal.ip_address (the 'ip_address' item above) is not specified or equal to "".
# networkInterface = "eth1"
# How many seconds before Socket.IO client sending a new ping packet. This value might be overwrote by client side.
# ping_interval = 25 #default: undefined
# How many seconds without a pong packet to consider the Socket.IO connection closed. This value might be overwrote by client side.
# ping_timeout = 60 #default: undefined
# Life time for reconnection ticket. Unit: second.
reconnection_ticket_lifetime = 600 #default: 600
# Client will leave conference if it cannot reconnect to Socket.IO server after |reconnection_timeout| seconds.
reconnection_timeout = 60 #default: 60

management_api/management_api.toml

keystorePath = "./cert/certificate.pfx"

superserviceID = "my superserviceID"

ssl = false #if use HTTPS

port = 3000 #default: 3000, port of server

numberOfProcess = 1 #default: 1

management_console/management_console.toml

[console]
#configuration for the management-console
keystorePath = "./cert/certificate.pfx"
ssl = false #if use HTTPS
port = 3300 #default: 3300, port of manage console server

[api]
#configuration of management-api server
secure = false #if server certificate is verified, set it to true.
host = "http://localhost:3000"

And I got an error after I start-all

starting app, stdout -> /home/ubuntu/Intel_CS_WebRTC.v.4.2/Release-v4.2/logs/app.stdout

Do I misunderstanding something? Any help will be very appreciated.
