L’applicazione Spring Boot Actuator non verrà avviata su Ubuntu VPS

Ho un backend Java che utilizza Spring Boot Actuator ma non verrà avviato su Digitalocean Ubuntu VPS. La stessa applicazione funziona bene sul mio Mac e su un altro PC Ubuntu.

szabolcs@SmartUpProd:~/smartup$ java -Xmx1536m -jar build/libs/smartup-backend-0.1.0.jar 

Inizia l’inizializzazione ma si ferma sempre nello stesso punto (nessuna eccezione, si blocca). Se provo a fermarlo a questo punto con ^C , non restituirà il guscio.

Questo è l’outoput:
