Hey there! THe method of troubleshooting the issue depends on what the error is when you try to access the site. I would start by checking the Apache logs at /etc/apache2/logs/error_log to see if there is anything helpful there. However, if it is a DNS error or redirect error of some sort, that would take us down a different troubleshooting path.

ok wait i will update soon after server is up, because now there is trouble in network

for now the cpanel and website running well, after we delete some account in whm. if in the future, there is 150 account/more, how many server's speciifcation should i provide?

I'm glad to hear things are working well. It's never really possible to say based on just the number of accounts as it only takes one resource-heavy domain to bring down an entire server. If you have a shared server and are worried about resource usage, I would recommend looking into the CloudLinux operating system so you can place limits on individual domains.
