ArcGIS Server Web Feature Service (WFS) behind reverse proxy does not work using the internal port 6443 for communication and returns the following error message, "Bad Gateway: The proxy server received an invalid response from an upstream server.".

Workaround

A possible workaround is to disable streaming. To update the service property via JSON, refer to the Disable Streaming property in the help topic https://developers.arcgis.com/rest/enterprise-administration/server/extensiontypes.htm for more information.

The option to disable streaming is available in ArcGIS Server Manager as of version 11.1. Here are the steps to follow in ArcGIS Server Manager.

1. In a browser, open ArcGIS Server Manager.
2. Click the service to edit.
3. Under Capabilities, select WFS.
4. Scroll to the bottom of the page and check the Disable Streaming check box.
5. Save and restart the service unless the datasets are very large; there supposedly is no significant difference by disabling streaming.

For large datasets meant for streaming purposes, the workaround is to put an ArcGIS Web Adaptor between the reverse proxy and ArcGIS Server. Reference ArcGIS Server in ProxyPass and ProxyPassReverse with the ArcGIS Web Adaptor URL to disable streaming.
