Hi all,


I read doc and see answers in this forum about a similar problem, but i doesn't see the same characteristics that my problem.


I am using a VM. I rename the machine "alma" and add a DNS "" like ESRI support says to me.


I install ArcGIS Server and etc. by ArcGIS Enterprise Builder in this VM, the installation works perfectly.


But, when I try to access to server from another PC i need to write the IP of VM instead of to access to server, so I need to write https://XX.XX.XX.XXX:6443/arcgis/manager/site.html instead of or . My first question if it's logic or not ? And why ?


Also, there is the big problem. When I also try to access to Portal from outside the VM, if I write or or https://XX.XX.XX.XXX:7443/portal/home/organization.html there is the result :

 and few seconds later this ->


If i write this https://XX.XX.XX.XXX/portal/home/organization.html this is the result : 



So, we need to access to Portal from outside our VM and I don't know what to do to fix this problem. Because in fact if I install all the products with ArcGIS Enterprise Builder, this do a correct installation, right ? Because I see in doc that it can be a problem with WebAdaptor configuration name : but I see and the name of WA is the correct so it can't be that. 


Thanks in advance and I hope we can fix it.
