registering third party rest service with DNS/https enabled with SC throws error <java.lang.IllegalArgumentException: port not specified.>

We have a third party rest service with https enabled eg:`https://pos-dev.test.com`. We can register it to the service center.
But the gateway cannot route to it at run time and it is failing with the below error.

`
java.lang.IllegalArgumentException: port not specified.
`
And the service center instance is disabled eventually. Getting this error

`
{
"message": "No available address found."
}
`
How to handle this? Urgent info required

Start by reproducing registration and gateway routing for the HTTPS DNS service described in the issue, then trace the `port not specified` exception through service discovery and gateway routing. Done means the service remains enabled, the gateway routes requests successfully, and the `No available address found` error no longer occurs.
