I upgraded our ArcGIS Enterprise 11.0 install to 11.1 last week and ever since then secure services are causing the print service to crash. The error message is "Error executing tool. Export Web Map Task : Failed to create layer from service at <SECURE SERVICE URL HERE>. Failed to execute (Export Web Map)."
This happens with the built in PrintingTools service and with custom print services. If there are no secure services in the map the all of the print services work as expected. Our setup uses short term tokens but they do not seem to be passed from the web map to the print service. I say this because verbose logging recorded "Request user: Anonymouse user, Service: <SERVICE PATH HERE>" when the print service tried to access the secure service.
Is anyone else experiencing this issue?
