Hi @Stephan_Mestach ,
I can explain both of the behaviours you are seeing.
Firstly, you are seeing redirects to the im subdomain as we have moved our play infrastructure to a new system based on Kubernetes. In this migration phase we are trying to simply redirect things from the old play domain. The Kubernetes system has some limitations on naming conventions, so the URLs are a little different.
Secondly, 2.40 is not set up as a redirect, because we started dropping the “2.” with the release of version 40, and also reflected that in our instances on play. If you try to navigate to https://play.dhis2.org/40 you will end up where you expect. However, it was a bit of an oversight that we didn’t also add the redirects in case folks try to navigate to /2.40 - and that is something we can add easily.
Kind regards,
Phil
