In this guide, we will show you an easy way to fix this problem and start accessing your emails again without any trouble. Just follow our clear instructions step by step, and you'll be able to solve the issue and use Roundcube Webmail on cPanel like before.

1. Check Email Account Settings: 

Double-check your email account settings in Roundcube to ensure they are correct:

Step 1: Log in to your cPanel account.

Step 2: Go to the Email section and click on Email Accounts.

Step 3: Find the email account having issues and click on Configure Mail Client.

Step 4: Make sure the incoming and outgoing server settings are correct. This includes the server address (like mail.yourdomain.com), port numbers (e.g., 993 for IMAP or 465 for SMTP), and security type (SSL/TLS or None).

2. Check Network Connectivity:

Ensure your internet connection is strong and working well. A slow or unstable connection might stop Roundcube from getting emails. Test by visiting other websites to confirm your internet is working properly.

3. Check Server/Error Logs:

Check the logs on your cPanel account or server for any error messages related to fetching emails. Look for specific codes or messages that can help understand the problem.

Step 1: Log in to cPanel.

Step 2: Go to the Metric section and click on Errors.

Step 3: Look at the error box and error list. Check for messages about email problems. See if there are specific error codes or messages that explain the issue

4. Update Roundcube:

Make sure you have the latest version of Roundcube. Check for updates in cPanel's software section and install them if needed. Newer versions often have fixes for problems and make Roundcube work better.

5. Disable Firewall:

To fix issues with accessing Roundcube Webmail, try turning off any firewall or antivirus software on your computer. Sometimes, these security programs can cause problems with the email service.

A) Turn off and Turn on ConfigServer Firewall from WHM Panel

Follow these steps to disable or enable ConfigServer Firewall (CSF) in WHM:

Step 1: Log in to your WHM Panel.

Step 2: Search for "firewall" in the search box and select the result. Go to the Plugins section and click on "ConfigServer Security & Firewall."

Note: This option may not be available if CSF is not installed on your VPS or dedicated server. Contact your hosting provider if you need assistance enabling it.

Step 3: Navigate to the "CSF - ConfigServer Firewall" section and choose "Firewall Disable" to turn it off.

Step 4: You'll receive a confirmation message after disabling the CSF firewall.

B) Turn off and on ConfigServer Firewall from the terminal:

To disable or enable ConfigServer Firewall (CSF) from the terminal, follow these steps:

Step 1: Log in to your VPS or dedicated server via SSH as the root user.

Step 2: Open the terminal and enter the command to disable CSF firewall:

csf -x

These commands will disable the CSF firewall and show the respective output in the terminal.

6. Check Email Account Quota:

Check to make sure your email account has not used up all its storage space. If it has, you can delete unnecessary emails or increase the storage limit. 

When you set up email accounts in cPanel, you specify how much storage each account can use. Sometimes, you might need to adjust this quota to accommodate more emails or reduce it if the account doesn't receive many emails. Follow these steps to change the mailbox quota in cPanel:

Step 1: Log in to your cPanel account.

Step 2: Click " Email Accounts " Under the Mail section."

Step 3: Find the email account you want to modify. If the quota is exceeded, it will be highlighted in red under the Storage section. Click on "Manage."

Step 4: In the Storage section, enter the new storage size for the mailbox quota in the allocated Storage space field.

Step 5: Click "Update Email Settings" to save the changes.

7. Disable Browser Extensions

Some browser extensions or add-ons might cause problems with Roundcube. Try turning them off temporarily to see if you can get your emails.

Here's how to disable extensions in Google Chrome:

Step 1: Open Google Chrome and click the three-dot menu icon in the top-right corner.

Step 2: After that, go to the Extensions option and click on the Manage Extension option.

Step 3: Simply click the toggle button next to the extension you want to disable.

8. Clear Web Browser Cache

Sometimes, stored data like cache and cookies can cause issues with Roundcube. Try clearing them from your browser before trying Roundcube again.

Clearing Browser Cache in Google Chrome:

Step 1: Open Google Chrome and click the vertical ellipsis button at the top-right corner.

Step 2: Choose "Clear browsing data."

Step 3: In the pop-up window, select a time range from the drop-down menu. Choosing "All time" clears all browsing history, cookies, and cached files.

Step 4: Check or uncheck boxes based on what you want to clear. To clear only the cache, check "Cached images and files."

Step 5: Click "Clear data."

9. Contact Hosting Provider Support:

If you've exhausted all troubleshooting steps and still cannot fetch emails in Roundcube, reach out to your hosting provider's technical support team. Provide them with details about the issue and any error messages encountered for further investigation.
