Cannot access docker container exposed port. Can ping but cannot telnet - docker

Question

I am trying to create an apache container in docker by following below link:
https://www.assistanz.com/installing-apache-web-server-in-windows-container-using-docker-file/
Version Details:
Host OS: Windows Server 2016 (VMWare virtualized machine)
Docker Version:
PS C:\Windows\system32> docker version
Client:
Version: 17.06.2-ee-16
API version: 1.30
Go version: go1.8.7
Git commit: 9ef4f0a
Built: Thu Jul 26 16:43:19 2018
OS/Arch: windows/amd64
Server:
Engine:
Version: 17.06.2-ee-16
API version: 1.30 (minimum version 1.24)
Go version: go1.8.7
Git commit: 9ef4f0a
Built: Thu Jul 26 16:52:17 2018
OS/Arch: windows/amd64
Experimental: false
I managed to create the container and run it with below command:
docker run -it -p 8080:80 apache powershell
PS C:\> ipconfig
Windows IP Configuration
Ethernet adapter vEthernet (Container NIC 258c52dd):
Connection-specific DNS Suffix . :
Link-local IPv6 Address . . . . . : fe80::706a:94f1:9a6:6c49%31
IPv4 Address. . . . . . . . . . . : 172.21.60.107
Subnet Mask . . . . . . . . . . . : 255.255.240.0
Default Gateway . . . . . . . . . : 172.21.48.1
Confirm if the apache is running on port 80 from inside of the container:
PS C:\> iwr http://localhost -usebasicparsing
StatusCode : 200
StatusDescription : OK
From host machine:
Access http://container-ip:80 and failed
PS C:\Windows\system32> iwr http://172.21.60.107:80 -usebasicparsing
iwr : Unable to connect to the remote server
Access http://host-ip:8080 and failed
PS C:\Windows\system32> iwr http://192.168.105.87:8080 -usebasicparsing
iwr : Unable to connect to the remote server
Tried to access from other pc using http://host-ip:8080 and also failed.
Few things that i did for troubleshooting:
Check container port forwarding by running docker ps
PS C:\Windows\system32> docker ps

Ping container IP from host => Okay
Telnet to container IP and Port from host => Failed
PS C:\Windows\system32> telnet 172.21.60.107 80
Connecting To 172.21.60.107...Could not open connection to the host, on port 80: Connect failed
Ping host IP from container => Failed
Have googled this issue and tried a lot of troubleshooting but seems like i could not find the solution for my issue. Most of the issue reported is due to the localhost loopback issue in window.
Any pointer on how to troubleshoot this further?
I am suspecting there is something blocking the container port. But i cant find it.
Thanks
