How to upgrade an Automation Server if Port 80 is closed and the Automation Server is placed behind a NAT router.
Getting error message when upgrading:
EcoStruxure Building Operation
- Building Operation Automation Server
- Building Operation Automation Server Premium
The problem is that the certificate are generated with the IP address off the Automation Server, and not the NAT Router IP.
The Device Administrator has the option to add SAN's (Subject Alternative Name) and not just the address of the server.
So add both the LAN and the WAN addresses in the SAN field when you generate the certificate and transfer to the server.
