Good afternoon.
I am struggling with an error related to Proxy Forward configuration on ArcGIS Server 11.1 and 10.9 on an On-premises server.
I have configured on ArcGIS Server Admin page the Home > system > properties , following the instructions from the Esri documentation page: Configure a forward proxy server with ArcGIS Server—ArcGIS Server | Documentation for ArcGIS Enterpr...
However, it does not take effect. I am trying to use the ArcGIS REST GP Service Utilities/PrintingTool/ExportWebMapTask, passing the Web Map as JSON, what uses an external URL to provide base maps.
Everything works when I access the URL via browser, proxy credentials are working. However, the base maps are not being exported when I do same request via ArcGIS REST GP Service, and blank JPEG is being generated.
Remark: when I remove the proxy configuration, nothing changes and the same empty JPEG is created, showing that these configurations are not taking any effect on the server. I didn't find any relevant log.
I would be very grateful if somebody can help with this issue.
Thank you!
