Firstly why use a single VS and not separated?
What is port 5609 used for?
What profiles have you applied on VS?

    Firstly why use a single VS and not separated? 443 for IIS and 5609 for Client component
    What is port 5609 used for? client component service(just used a random port for that service)
    What profiles have you applied on VS?  source address
