How to access ArcGIS Portal from server's local IP address instead of it's domain name?

[teofilosalgado]

Hi all!

Recently, we have been trying to implement a Portal for ArcGIS Server 10.7.1 instance in our infrastructure but we've stumbled in an issue with our NGINX reverse proxy service. Currently, on my Windows Server machine I can access my Portal trough the address: https://win-q0ejvg3fcqh.arcgis.local:7443/arcgis/home/index.html, but whenever I try to access it via my machine fixed local IP like so: https://192.168.25.209:7443/arcgis/home/index.html I get redirected to https://win-q0ejvg3fcqh.arcgis.local:7443/arcgis/home/index.html, my machine name and domain.

I need to be able to access my Portal from it's server local IP address so I can forward it's ports to the internet via my NGINX server, how could I accomplish that? Currently, I don't have any Web Adaptor installed and would really like to remain using my NGINX alone, due to company restrictions.

Any help will be very appreciated,
Cheers.

Hello João Victor Teófilo Salgado,

From what I understand you seem to need a method to have Portal using the private IP address for it's site configuration. This is typically done in our CloudFormation template deployments in AWS as well, and would need to be defined as a hostname.properties entry prior to site creation.

Additionally, there are more requirements for your NGINX and Portal configuration that are outlined in this documentation.

Customers tend to have the most issue with making sure the location headers in 30x responses are re-written to the WebContextURL, in my experience. When they have those issues, an easy workaround is to implement the web adaptors in front of Portal and Server and still have NGINX pass the traffic to those endpoints. If that is something you choose not to do, this information may be helpful as well.

Best of luck!

Hi Christopher,

I managed to make it work with plain NGINX, I was missing these headers in my configuration:
proxy_set_header X-Forwarded-Host $host:$server_port;

proxy_set_header X-Forwarded-Server $host;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
