What are requirements and typical configuration to establish a WinCC OA connection between ITC and WinCC OA ?
I’m using :
WinCC OA 3.17P013
ITC1500V3. Firmware 3.1.0 with the WinCC OA menu entry in connections list
I have started the http webclient on port 8080/8443 and I am able to connect desktop UI or mobile UI.
On the ITC I have a popup with an internal error 10. It doesn’t start the UI and I have no debug trace (-snd 2 -rcv 2) on the webclient controller.
Normally you only need to configure the connection parameters and the UI on the ITC should work.
The cause for the internal error 10 is not known. If you need further assistance please get in contact with your common WinCC OA support.

I had the same issue. Since the ITC does not have a hosts file it cannot resolve the hostname to the correct IP address. We then added a “config.webclient” file to the config folder of the server project with the following content:
[general]
proj_version = "3.17"
langs = "de_DE.utf8"
langs = "en_US.utf8"
dataHost = "192.168.120.2"
eventHost = "192.168.120.2"
<empty line>
..and also we were told that ITC1500 does not support HTTPS so we had to use HTTP only
I had a similar problem not so long ago.
You can use the hostnames on your'e winccOA connection setup on the ITC by definig a DNS server (for example on a virtual machine or real DNS server) which is visible on the ITC's and your server projects network so that the ITC knows where to look and resolve the hostname you provided.
Before that you need to look into ITC network settings and put the IP address of the DNS server. On the DNS side, you need to provide the hostname of the winccOA server which is running your project.
In the config file of your project instead of
