I installed the following esri products:
I activated a domain certificate which I attached port 443.
However, I only have access to ArcGIS portal locally

In addition I can not change the URL of the webdaptator as indicated in the following discussion: https://community.esri.com/thread/119888
Could you help me please?
If you go to https://<machine>.<domain>.com:7443/arcgis/portaladmin/security/oauth/getAppInfo, and then enter arcgisonline for the App ID, do you see your FQDN listed there?

Try to set the webcontext parameter just like this link:

the link is for linux but works with Windows too. Just set the webcontext parameter using Admin interface.
