To check whether the web api is running, I suggest you try to access web api from the hosted machine, will it work?
What is the user the windows service running under?
For this issue, it is usually caused by the firewall and the web api could not open the port due to permission issue.
I suggest you run below command to grant permission for the specific user.
netsh http add urlacl url=http://*:port/ user=<your user>
