Google Cloud only issues one managed certificate per domain at a time. Some people block port 80 'just because' to tighten security which is OK if everyone understands that's what's happening.ĭNS validation is strong alternative to http validation. In order to do that companies setup a MITM proxy that signs its own certificates. There is no special security benefit to blocking port 80 if you don't offer any other services on port 80 anyway. IIS and win-acme can share port 80, so you don't need to worry about that. Something else (like apache) is already running on port 80, so nothing else gets to use it.Your corporate firewall blocks port 80 or doesn't forward port 80 to that server.When installing the same certificate more than once, an appropriate error will be displayed.

This might indicate that the VMware VMCI (virtual machine communication interface) Bus Device driver is missing. You either need port 80 open (at least temporarily) or you need to use DNS validation. A quick Wireshark trace identified that the Certificate handshake was coming back as an Unknown CA. In a Windows virtual machine, the desktop toolbar or Device Manager shows a yellow circle with exclamation mark (yellow bang) indicating a device problem.
