After upgrading from 10.6 to 10.6.1 all of the Feature Analysis and Raster Analysis tools in Portal for ArcGIS fail with a blank error message box. However, monitoring the web traffic reveals this error message for all the tools: "Invalid value for parameter inputLayer- Details : Portal request self failed with error Proxy server got bad address from remote server (verify the server is running). (status code 504)."
This is the only thing I can find that is not working in our ArcGIS Enterprise deployment. I can still query, view, edit, publish hosted feature services. So I know that our Portal for ArcGIS and ArcGIS for Server can still talk to each other correctly. According to the web traffic the service that is supposed to hold the analysis results is created on ArcGIS for Server and it is successfully added to Portal for ArcGIS as an item. The tool then fails because the tool on ArcGIS for Server cannot access the input layer through Portal for ArcGIS.
Has anyone else seen this?
