When an agent in the cloud/DMZ attempts to download a package from the correct package server, the attempt fails. One or all of the following information/errors, or entries similar, appear in the client's agent logs:

Description:
Error while downloading package: No server found
-------------------------
When an attempt was made to open the above URL (with Internet Explorer) from the gateway machine the result was a warning that the certificate was not trusted.
If the option to continue anyway is selected an error was returned. 403 - Forbidden: Access is denied.
An examination of the certificate showed that it was from the wrong server. It was not the certificate from the specified Package Server, but (in this case) from the SMP server.
SMP 8.5 RU2
An entry existed in the gateway machine's hosts file (C:\Windows\System32\drivers\etc). The entry specified the SMP server's address as that of the Package Server.
Correct the entry in the hosts file giving it the correct address. After doing so clients began downloading successfully.
