SpringBoot Error creating bean in Spring boot in CentOS 8

I'm trying to use cuebot (opencue) in centos and can't deploy cuebot on the server with this error:

java -jar build/libs/cuebot.jar --datasource.cue-data-source.jdbc-url=jdbc:postgresql://$DB_HOST/$DB_NAME --datasource.cue-data-source.username=$DB_USER --datasource.cue-data-source.password=$DB_PASS --log.frame-log-root="${CUE_FS_ROOT}/logs"

I don't think this is a Spring Boot problem. Netty cannot bind to the port that com.imageworks.common.spring.remoting.GrpcServer has been configured to use. Bind failures can have a variety of reasons. For example:

• the user running the app does not have permission to bind to the configured port
• the configured port is already in use

If you'd like some more help diagnosing the problem, I would recommend following up on Stack Overflow. Also, please note that Spring Boot 2.2 has reached the end of its open source support period and you should upgrade to 2.3.x or 2.4.x as soon as possible.
