Many users have reported encountering this issue, which can be frustrating and hinder productivity. In this article, we'll delve into the root cause of the 'Econnrefused' error and provide a solution to get you back up and running.

The 'Econnrefused' error typically occurs when FileZilla is unable to establish a connection with your SMTP server, resulting in an 'undesirable exception.' This issue can be caused by various factors, including incorrect port numbers or software conflicts. In this case, the error message specifically mentions that the mail server port is bad, indicating that there may be an issue with the default port number being used.

To resolve this issue, you'll need to whitelist your SMTP server in FileZilla. This involves configuring the software to use a specific port number and address for your SMTP server. Here's how to do it:

1. Launch FileZilla and navigate to the 'Edit' menu.

3. In the 'Settings' window, click on the 'FTP' tab.

4. Scroll down to the 'Proxy' section and select the 'Use system proxy settings' option.

5. Click on the 'Apply' button to save your changes.

Next, you'll need to configure your SMTP server address and port number in FileZilla. To do this:

1. In the 'Edit' menu, select 'Settings' again.

2. This time, click on the 'SMTP' tab.

3. Enter your SMTP server address and port number in the corresponding fields.

4. Click on the 'Apply' button to save your changes.

By whitelisting your SMTP server in FileZilla, you should be able to establish a connection with your server without encountering any errors. If you're still experiencing issues, there may be other factors at play, such as software conflicts or network connectivity problems.

To troubleshoot these issues, try restarting your computer and checking for any software updates. You can also try using an alternate email client or SMTP server to see if the issue is specific to FileZilla or your current setup.

In conclusion, the 'Econnrefused' error in FileZilla is often caused by issues with the mail server port being used. By whitelisting your SMTP server and configuring the software correctly, you should be able to resolve this issue and get back to sending and receiving emails without any problems.
