Cause:
Corruption of underlying registry keys used in netsh commands
Note: Make sure no changes has been made to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\HTTP
Start REG_DWORD 0x00000003(3) should be enable
Start REG_DWORD 0x00000004(4) is disable. This is the wrong setting.
Resolution:
1. Open Registry Editor on Windows OS
Go to Windows Start menu >> Run >> regedit
2. Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\HTTP\Parameters\SslBindingInfo
Delete all the entries under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\HTTP\Parameters\SslBindingInfo
Please make a backup before deleting all of the keys.
