Changing ArcGIS portal DNS alias post installation -

[LakshmananVenkatesan]

All,

I have successfully installed and configured ArcGIS 10.6 (single site deployment) ArcGIS server federated with Portal. This is almost brandnew portal. Now business team wants change in application url.i.e.  DNS alias  needs to be changed.

Portal url:  https://gisportal.domain.com/portal/home - now business asks me to change to https://gishub.domain.com/portal/home. I would like to know the basic high level steps for this change.

I got a new signed SSL certificate for gishub.domain.com and updated new DNS alais to machine name. Do I just need to reconfigure web adaptor with new dns alais or any

other steps involved,.

Hey,

I solved this problem. I opened the portal to external users from the modem interface. But ,I can't access the server manager outside the server. After entering the information, I get the attached error.Can you help me?

Regards

I am having a similar issue with portal. During the install process, I did not see anywhere to enter a preferred machine name; Portal (11.0) just used the internal name (X.Y.local), and does not appear to have anyplace in the portaladmin/machine to change it. My SSL certificate only includes the external DNS name. So, when I try to access the portal or the admin site via the DNS alias, it automatically forwards to the internal name (which won't work outside our intranet), throwing all the HTTPS security warnings. I have tried using the WebContextURL property, but maybe I'm not doing it right. I am not using WebAdaptor.

In ArcGIS Server, it is easy to change the machine address to solve this problem, but it appears to be impossible in Portal. What is the workaround?

Nevermind. Found the answer at the bottom of https://enterprise.arcgis.com/en/portal/latest/install/windows/installing-portal-for-arcgis.htm. The heading was misleading because I don't have multiple cards or DNS names, but it worked.
