Once the ArcGIS Video Server site has been created, you must install ArcGIS Web Adaptor and register it with ArcGIS Video Server.
ArcGIS Web Adaptor provides a connection between the ArcGIS Enterprise web server and the ArcGIS Video Server site. It allows you to specify the port, address, and authentication settings for incoming requests.
ArcGIS Web Adaptor for ArcGIS Video Server must be configured to use port 443 instead of port 80. Configuring ArcGIS Web Adaptor to use port 443 means you must bind the appropriate certificate to the port through IIS, your web server, or a reverse proxy server.
The setup steps for ArcGIS Web Adaptor can differ depending on the type of web server (IIS, Java on Windows, or Java on Linux) on which it's being installed.
Once ArcGIS Web Adaptor is installed and configured with the ArcGIS Video Server site, federate the site with your portal.
