iaas-service is blank and get http 402 error in Infrastructure page.

I install VCAC 6.2 on Windows2012R2 and MSSQL2012SP1

There is no error when I install iaas.

Then:

When I check https://va:5480. The issa-service status is blank.

When I chekc https://va/component-registry/services/status/current. And I get below information

Exception during remote status retrieval for url: https://iaas/WAPI/api/status. Error Message I/O error on GET request for "https://iaas/WAPI/api/status":Connection reset; nested exception is java.net.SocketException: Connection reset.

And When I check https://iaas/WAPI/api/status. I can get correct information.

So, how can I track this error.

Thanks.
