I have changed my login port 8090 to 7788, Now I want to use 8090 port for another application.
Port in the firewall below.
But when I am trying from outside to check the port I am getting like below:

How to open this port now.
Using latest cyberpanel on Ubuntu 20.04
Hello @nawaze
See /usr/local/lsws/conf/httpd_config.conf
or /usr/local/lsws/conf/httpd_config.xml
for litespeed if port is still there
Use firewalld-cmd to open the port permanently
firewall-cmd --permanent --zone=public --add-port=7171/tcp
firewall-cmd --complete-reload

is it ok if i want to add the port 7788 to httpd_config.conf?
Why do you feel you need to add a port there for your website ?
To work with open ports in your existing websites you just need to add a context to vHost config that is recommended way. You website should handle which port it wishes to use
a python application running on the server.
Yes
Is there any way to just open a port?
Port is not blocked by cyberpanel only firewall and security softwares can do this. Review your security protocols. Maybe ask your server provider if they block that port for any reason and I hardly doubt they do.
Now 7788 port is closed, if i change the login port to 7788 then it become open. So i think port Isn’t blocked from the provider
Manually add port in firewall or CSF page.
