Increase elastic IP limit:
To verify how many Elastic IP addresses are in use
Open the Amazon EC2 console at https://console.aws.amazon.com/ec2/
and choose Elastic IPs from the navigation pane.
To verify your current account limit for Elastic IP addresses
You can verify your limit in either the Amazon EC2 console or the Service Quotas console. Do one of the following:
Open the Amazon EC2 console at https://console.aws.amazon.com/ec2/
Choose Limits from the navigation pane, and then enter IP in the search field. The limit is EC2-VPC Elastic IPs. If you have access to EC2-Classic, there is an additional limit, EC2-Classic Elastic IPs.
Open the Service Quotas console at https://console.aws.amazon.com/servicequotas/
On the Dashboard, choose Amazon Elastic Compute Cloud (Amazon EC2). If Amazon Elastic Compute Cloud (Amazon EC2) is not listed on the Dashboard, choose AWS services, enter EC2 in the search field, and then choose Amazon Elastic Compute Cloud (Amazon EC2).
On the Amazon EC2 service quotas page, enter IP in the search field. The limit is EC2-VPC Elastic IPs. If you have access to EC2-Classic, there is an additional limit, EC2-Classic Elastic IPs. For more information, choose the limit.
If you think your architecture warrants additional Elastic IP addresses, you can request a quota increase directly from the Service Quotas console.

Greylisting generates a temporary error on purpose and waits for the sending server to come back later and try to deliver the email again.
If you are receiving this error after send an email to another external destination email address this means, the same way we have in our server, they have a spam blocking system which use Greylisting (or Delaying) method to stop spam.
This method is based in the idea that a spam server will not send you the same message more than once in a period of time.
Greylisting generates a temporary error on purpose and waits for the sending server to come back later and try to deliver the email again.
A normal server, waits a while, tries again and then succeeds in delivering the mail. A mass email engine (spammer) tries one time and then the email is lost forever.
The greylisting mechanism keeps a database of approved senders, each consisting of sender address, recipient address and the IP address of the sending email server. When a new combination is found for the first time, a message looking something like this is sent back to the sending email
server:
451 4.7.1 Please try again later
If the sending email server tries again before the X minutes has passed, it will receive a temporary error again. After the X minutes has passed and the sending server tries again, the email will pass and the sender triplet will be registered as “whitelisted”. That means that subsequent emails from the same sender to the same recipient will be delivered without delay.
If someone sending you an email is receiving this error then this means you have enabled the Delaying Filter in the “ASSP Spam and Virus Protection” section in your cPanel. You can read more about the Enterprise Anti SPAM system we have installed in all our cPanel servers searching about it in this Knowledgebase.
This means our Server is unable to connect to a remote server. This could be because the remote server is offline or your server has been offline. … The retry time will be reached and the server won’t try to deliver the message until the retry time has expired

Website down: Troubleshooting steps
– Firstly, we have to check disk usage of the account if it is 100% or near to it at cpm > server settings > disk management.
If it is full then we have to ask cm to free up space by deleting unwanted files or expand the storage by purchasing more space.
If webmail, filemanager, MySQL DBs or any other tool is not working we have to check disk usage on the account.
If customer is not aware of the file/folder where disk is used most, we can either run ssh command to know the space or have escalation (since they have root access)
*There is a case that customer has purchased SAN Storage yet they get error, in that case we should check if they have mounted the purchased storage or not,
we usually recommend them to mount it to /backup, /tmp or /home/username mounting point.
– Rest troubleshooting is same as Shared accounts, which includes db error, http 500 error, 403 permission error etc.,
Email: Troubleshooting steps
Getting error while logging into webmail: Since they are in Dedicated servers, webmail login url will be http://server.domain.com:2095 as domain.com/webmail and other urls will not work.
550 error – This is typically a bounce due to bad mail configuration for the servers mail exchangers.
You will need to modify the mail configuration via: WHM>DNS Functions>Edit DNS Zone>Email Routing settings. Please Update this setting to “Local Mail Exchanger”.
SMTP connection error – This is an issue affecting connectivity of mail clients to a VPS.
When setting up the mail client, incoming mail will connect and function properly but SMTP will fail.
By default cPanel has a setting within WHM set to use SSL for SMTP services. You can disable this function via: whm>exim configuration manager>Security>Require clients to connect with SSL.
email not working: check exim status ->status exim <IP>
status httpd <IP>
If both are locked, then account is deactivated due to malware.
SSL issues: Troubleshooting steps
We can install SSL just like in Shared, and the troubleshoot is same as well.
Error while accessing manual ssl tool from cpm, what I found is renaming “ssl” folder in filemanager (it will remove all ssl certs uploaded as we rename the folder itself,
we can still find Certs and keys from renamed folder to reinstall ssl) will remove the error by occurring than escalating and creating slow Tickets.
Certificate is not found on this box error while trying to activate ssl from cPanel: To fix this we have to install a self-signed ssl from SSL manager,
SSL manager > Certificates > scroll down > fill up the domain and customer details starting from Description (which will be domain name with and without www) > Generate >
this will generate new set of SSL Certificate and Keys, we have to install it as 3rd party ssl, once it is installed then we will be able to activate ssl from cPanel > addons > ssl certificates.
Log Locations:
There are two main locations where logs are kept on Dedicated and VPS servers. The /usr/local/cpanel/logs directory and the /var/log/ directory. Here is a list of the logs common to each directory.
/usr/local/cPanel/logs
access_log: cPanel access log for both cPanel and WHM
error_log: cPanel error log
license_log: cPanel license log
login_log: cPanel user login log
melange.log: cPanel chat server log
melange_msg.log: cPanel chat server message log
stats_log: cPanel web stats log
/var/log/
chkservd.log: chkservd service log

maillog: Transaction and login log for all mail services
pgsql: PostgreSQL log file
cPanel keeps the domain weblogs in the /usr/local/cpanel/domlogs directory for each domain name that is hosted on the server. This includes FTP transfer logs for each account.
Editing the PHP.INI using MultiPHP INI Editor:Log into WHM
Search ‘PHP’ In the top left Search Bar
Look for the ‘MultiPHP INI Editor’ and select it
From the dropdown, select which version of PHP to change the INI for.-Check the ‘MultiPHP Manager’ to verify which PHP version is active
Under Basic Mode, there is an option to edit most commonly changed variables- memory_limit; max_upload_size; max_execution_time; max_input_vars;-The most common one not in Basic mode is post_max_size.
Once the change has been made please select ‘Save’
Restart the PHP-FPM service for Apache under Restart Services.

WHM >> Account Functions >> Modify an Account >> Under Resource Limits >> Maximum Hourly Email by Domain Relayed.
Domain issue:
Remote domains(unable to add domains to existing cPanel) – This is caused by a default setting that will not allow domains not pointed to the server to be added to the DNS configuration.
You can disable this feature WHM > Server Configuration > Tweak Settings > Allow Remote Domains. Enabling this will allow you to add domains that are currently not pointed to the server.
Unable to Addon/Alias/Parked due to limits – This is due to default limit being set to 0 or reaching the limit outlined in WHM.
You can modify this limit via Home > Account Functions > Modify an Account
/How to Create Resold Accounts:
There are 2 ways you can do this, but the most consistent is through the cPanel:
1. Log into Control Panel.
2. Select Reseller.
3. Select ‘Create Account’.
You’ll need 4 things from the customer
->Domain Name
->Email Address
->Password (or generate one)
->Package
->Opt. Additional Features (SSL, Dedi IP)
Click ‘Create’ and the account will be scheduled to be created and assigned a Username. If it doesn’t work, and throws a specific error, there’s option 2.
Method 2:
Access the Reseller WHM in ‘Reseller Management Tools’B. Search “Create” in the search bar on the left under ‘WHM’C. Under Account Functions, you’ll see Create an AccountD. Enter the same information as above, and Create the account.
