Deploying crashed

Hello, i'm facing a problem when deploying my spring boot application to railway, my application works perfect locally but i get error of communication link failure and i can't find the solution,

this is my application properties :

spring.datasource.url=jdbc:mysql://containers-us-west-53.railway.app:5925/railway?useUnicode=true&useJDBCCompliantTimezoneShift=true&useLegacyDatetimeCode=false&serverTimezone=UTC
spring.main.allow-bean-definition-overriding=true
spring.application.name=generated


spring.datasource.username=root

spring.datasource.password=my password

spring.datasource.testWhileIdle=true
spring.datasource.validationQuery=SELECT 1

spring.jpa.show-sql=true

spring.jpa.hibernate.ddl-auto=update
spring.jpa.hibernate.naming.implicit-strategy=org.hibernate.boot.model.naming.ImplicitNamingStrategyLegacyHbmImpl
springdoc.enable-native-support=true
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.MySQLDialect


server.port = 8080

where can i find project ID

I don't know java so I'm not much help, but someone who does know java will need to see some error logs
