WSUS Post Installation fail on Windows server 2012 R2

Hello,

Trying to setup WSUS role on 2012R2. I have set it up with default config. When running the post installation task I get an error

I had already try these but still cannot fix it:
1. Turn off firewall and anti-virus
2. Uninstall IIS, WSUS and WID
3. Delete WSUS website in IIS

Any ideas?
Thanks
