Hi,

We are having issues with a custom printing service used in a ArcGIS Web AppBuilder application in our Acceptance environment.

This printing service is configured as synchronous .

We receive a Timeout exceeded message.

The architecture in Acceptance is a High Availability configuration.

All ArcGIS Enterprise software versions are 10.8.1 installed on Windows Server 2012 R2 machines.

The two ArcGIS Portal servers are configured using a Web Adaptor as the load balancer.

The two ArcGIS Server servers are configured using a physical load balancer of F5 type, no Web Adaptor configured for ArcGIS Server.

We also have an Integration environment configured using 4 servers.

In this configuration, ArcGIS Portal and ArcGIS Server are configured using a Web Adaptor.

In both environments, we have configured a custom printing service as described here : Share custom layouts for printing from ArcGIS Pro—ArcGIS Server | Documentation for ArcGIS Enterpris...

The access to all ArcGIS Portal environments are configured with Web-tier authentication : Print maps that contain secured services—ArcGIS Server | Documentation for ArcGIS Enterprise

No Web-tier authentication is configured for ArcGIS Server.

The services we try to print are shared with Organization, not Public in all ArcGIS Portals.

When we print a map with one of those services in Integration environment, print is OK.

When we print a map with one of those services in Acceptance environment, print is not OK. We receive a timeout exceeded message.

If we try to print a Public service in Acceptance, print is OK.

See below for configuration details.

Do we have to configure the physical F5 load balancer in Acceptance so that credentials are transmitted correctly from ArcGIS Portals to ArcGIS Servers ? Do we need WebAdaptors between the F5 load balancer and ArcGIS Servers ?

Do we have to embed credentials in a new printing web tool as described here : use the ImportCredentials function in ArcPy (arcgis.com) ?

Kind regards,

Hervé
