Answer 1

Are you sure the port is opened?

You can check this using telnet client

telnet machine 8080

If the port is not opened then you can check the exception details to see what is wrong.

If your HTTP-based service is started under non-administrator account then most likely you need to register it with the command like the following

netsh http add urlacl url=http://+:8080/AuditService user=mylocaluser

您与管理员打开命令提示符并输入以下文本：

netsh http add urlacl url=http://+:8080/AuditService user=Everyone
