Can't ssh console

@thomas I know I already marked your previous answer as solution, but I’d appreciate if you could also shed some light into this: what other alternative do I have to see the logs of my deployed app?
The online fly.io logs or the flyctl logs --verbose are pretty unreliable for me (and made me waste more hours than I would like to admit). For my current very simple python UDP app if it is running and I ssh into it, it won’t show me the printed logs, and if I try to manually start it from the ssh console it will get in conflict with the app that is already running, since the address and port are already taken.
