We are currently installing a new instance of SDL Web 8.5. During the installation, we are trying to install TMS (we are upgrading an old SDL Tridion installation).
When running the installer, we fill in the TMS connection details, however, we get the following error: "The underlying connection was closed: An unexpected error occurred on send".
We are able to open the url of the server address. We also installed the certificate on the new server.
Is there some configuration we are missing?
