I'm having trouble connecting my spring boot app with the postgres isntance they are both starting correctly and I set the env variables in my spring app to

SPRINGDATASOURCEURL=jdbc:postgresql://monorail.proxy.rlwy.net:48165/tiss-postgres
SPRINGDATASOURCEUSERNAME=postgres
SPRINGDATASOURCEPASSWORD=mypw

but I get

Caused by: org.postgresql.util.PSQLException: FATAL: database "tiss-postgres" does not exist
