@Andrea_Giovacchini

shouldn’t changing the app.yml have an effect on the ports used

Yes, but you have to ./launcher rebuild app (or maybe ./launcher destroy app;./launcher start app). My guess is that you just edited the file and then restarted the container that already had the ports configured.
