 @lucadelu,

 I've tested on a plain vanilla new version https://talks.dev.osgeo.org

 this one has a separate nginx in the docker-compose.

 Let me know once you are done with your training today and I'll try to
 upgrade https://talks.staging.osgeo.org the same way I did
 talks.dev.osgeo.org and have you check it out before I deploy the upgrade
 to production.
