Even if your security group allows traffic, the instance itself might have a local firewall blocking it. Make sure the instance's firewall (iptables on Linux, Windows Firewall) has a rule allowing traffic on port 5000.
Check your Flask application to listen on 0.0.0.0 to accept connections on all interfaces.
if __name__ == "__main__":
app.run(host='0.0.0.0', port=5000)

Which OS is this, and is there a host-based firewall?
This might be ufw
on Ubuntu, or firewalld
on RHEL/CentOS/Fedora. Check port 5000 is open in its config.
