I have installed Vaadin CC (1.1.0) into kubernetes inside Docker desktop. I managed to login into Vaadin CC via http://control.local. After several days I decided to deploy a sample application and tried to login Vaadin CC again, but now Vaadin CC automtically redirects from http://control.local to https://control.local and fails with an error:
503 Service Temporarily Unavailable
nginx
I checked that is not a problem of a web browser: I suppressed switching from http to https in chrome. Also I have tried firefox with the same result.
