Our Watson app based on Dialogue Service was running this morning, and this app has many users. Then I saw your 2017 DevOps tutorials video on Youtube on using Auto Scaling Service to scale web apps on Bluemix. Then I connected our this Watson app with the Auto Scaling app. Then, right way, this watson app is crashed. So, I tried to unbind this Auto Scaling App from this Watson app, but it cannot be done. So, I had to delete this Auto Scaling Service from this Watson app.
After that, this Watson app cannot be started. Hope that Bluemix cloud team and Auto Scaling Service team reply here soon. If anybody also have got such horrible experiences with the Bluemix cloud Auto Scaling Service, I also like to hear some input from you. Thank you !
