How can I modify the server configuration to increase the timeout for a Cloud Foundry app in IBM Cloud?
I have a Python/Flask service on IBM Cloud/Cloud Foundry that may take over a minute to complete. The server sends a time-out error after one minute.
The error returned by the server is: "500: Failed to establish a backside connection" This message also appears in another thread: "500 Error: Failed to establish a backside connection" - Bluemix Selenium Tests. And the answer posits that it is due to a server-side timout, which can be remedied by updating server.xml.
How it is called: The service exposes a Swagger page. Using that page, an HTTPS POST message is sent to the service.
Stack trace from the log. Swagger page is successfully rendered, but the POST initiated on the Swagger page fails:
