After upgrade from MongoDB 4.x to 5.0.2 shows Connection Refused trying to connect BD from Private Network

I have upgraded my MongoDB from 4.x to 5.0.2 into a Ubuntu 20.04 system. This server is an AWS EC2 Instance. After upgrade I can't connect my applications from other ec2 instances using the same Network (private network), but I can connect using my public ip address by mongo compass. So, I have ensured that my Mongo DB server is into a same network from other instances and it have the correct entrance into my Inbound Rules at Security Group. I have checked my /etc/mongod.conf

# mongod.conf

# for documentation of all options, see:
#   http://docs.mongodb.org/manual/reference/configuration-options/

# Where and how to store data.
storage:
  dbPath: /data/db
  journal:
    enabled: true
#  engine:
#  wiredTiger:

# where to write logging data.
systemLog:
  destination: file
  logAppend: true
  path: /sys/log/mongod.log

# network interfaces
net:
  port: 27017
  bindIp: 0.0.0.0


# how the process runs
processManagement:
  timeZoneInfo: /usr/share/zoneinfo

Someone has had this problem or have any idea that how I can fix it?

Does this answer your question? [What causes the 'Connection Refused' message?](https://serverfault.com/questions/725262/what-causes-the-connection-refused-message)

I sit in a Tesla and translated this thread with Ai:

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
