Cause

This issue occurs if the Authentication Proxy service is not listening on port 51915.

Resolution

To resolve this issue, change the Authentication Proxy service to port 51915.

 

To change the Authentication Proxy service to port 51915:

1. Log in to the server that is running the vSphere Authentication Proxy as an administrative user. Click Start > Run, type services.msc and click OK.
2. Right-click Authentication Proxy Services and click Stop.
3. Open Server Manager and navigate to Roles > Web Server > Internet Authentication Services > Computer Account Manager > Bindings.
4. Select https and select Edit Change Port.
5. Change the current port to 51915.
6. Modify the vmconfig-cam.xml file, located at C:\ProgramData\VMware\vSphere Authentication Proxy\, using the text editor. Set the port to 51915.
7. Open the C:\ProgramData\VMware\vSphere Authentication Proxy\ssl directory and remove any host-XX files.
8. Restart the Authentication Proxy Services service.

Additional Information

Currently vSphere Authentication Proxy supports only IIS 6 and IIS 7. Windows 2012 and 2012 R2 running IIS 8.x are not supported.
