WinCC OA Server on Azure VM

[daniel.ponader]

Dear all,

we tried for a test installation to run a project on a Microsoft Azure VM with Windows 10 Pro. Installation of WinCC OA (3.16 P20) and the project is fine. Directly on the VM it runs. After this we wanted to connect via Desktop UI, the VM has a fixed public IP and also an URL. The http and also the https server connection works without any problem, so it's possible to dowload the Desktop UI Install package from the VM and also to establish the connection to the projects web server via Desktop UI. But the connection to the data manager fails. Config.webclient of the project contains the entries for event and data with the respective public ip or the url (we tried both with the same result). We also added the server entries in the project config file for the multiplexing proxy. I also added the incoming connection rules at the VMs and also at the cloud firewall (open ports 4800-6000),just for testing. Basically only the 5678 is needed for the proxy, am I right?
The issue seems to be that the VM itself doesn't know it's public IP and also not it's Url and all routing and forwarding it's managed in the azure infrastructure so that the multiplexing proxy cannot reach data and event manager via public IP or Url. Is there a possibility to configure the multiplexing proxy in the way that it locally on the VM with the private IP address or the host name and it's still reachable via public IP/Url?

Beside of this I read that demo.etm.at runs on a AWS EC2 VM is there a documentation available (how it's configured, which resources are required, etc.)

Thanks a lot
Best regards

Hi again,

I just found a solution...I just added the Url to tho windows hosts file and connected it with 127.0.0.1, this works fine.
