I have configured it on a machine or portal and arcgis for server, I am using the standard certificate, which is installed along with the application. I am trying to make publications on others machines within my own domain, but timeout errors are occurring. What could be happening?
Using something like Test-NetConnection to confirm you can access the machine and port outside of ArcGIS applications. It may be a firewall or some other network issue is preventing your client from connecting.
