Hi I have a problem when opening the ports in google cloud vps in centos 7 the other ports open normal but port 6900 does not open, I would like to know any suggestions to open this port? ps: ports 5121 and 6121 are already in the firewall open normally but 6900 does not open

 
firewall-cmd --zone=public --permanent --add-port=6900/tcp
firewall-cmd --zone=public --permanent --add-port=6121/tcp
firewall-cmd --zone=public --permanent --add-port=5121/tcp
firewall-cmd --reload


try maybe firewall is preventing it.

Sir in the console it tells me that it is open but when I try to log the server it keeps saying that it is closed as in the port checker: C

PD : [Status]: Connecting to MY IP:6900
[Error]: make_connection: connect failed (socket #6, error 111: Connection refused

it must be the database credentials try 
 

Code: 
mysql -u root
CREATE USER 's1'@'localhost' IDENTIFIED BY 'p1';
GRANT ALL ON `your_game_database`.* TO 's1'@'localhost';
GRANT ALL ON `your_log_database`.* TO 's1'@'localhost';
FLUSH PRIVILEGES;

You should allow first using Iptables port 6900

# iptables -I INPUT 1 -p tcp --dport 6900 -j ACCEPT

# iptables -A INPUT -s 192.168.0.1 -p tcp --dport 6900 -i eth0 -j ACCEPT  ------ change the IP hostname

# iptables-save

After that allow firewall cmd command

firewall-cmd --zone=public --permanent --add-port=6900/tcp

firewall-cmd --zone=public --permanent --add-port=6121/tcp

firewall-cmd --zone=public --permanent --add-port=5121/tcp

firewall-cmd --reload
