Resolving Temporary IP Blocks Due to Failed Login Attempts Print

  • 0

At Domain Registration India Private Limited, we prioritize the security of our clients' accounts. One of the security measures we employ is temporarily blocking IP addresses that have multiple failed login attempts within a short period (16 failed attempts in the last hour). This article will guide you through understanding and resolving such temporary IP blocks.

Understanding Temporary IP Blocks

When your IP address is temporarily blocked, it means our server detected multiple failed login attempts from your IP within a short time. This is a precaution to protect your account from potential unauthorized access. Temporary blocks are automatically removed after one hour.

Temporary IP blocks can be triggered by failed login attempts on various services, including:

  • IMAP
  • SSH
  • FTP
  • POP3D
  • CPANEL login

Common Causes and Solutions

Here are some common causes of failed login attempts and steps to resolve them:

  1. Incorrect Client Configuration

    • Ensure that your clients (e.g., email client, FTP client) are configured with the correct credentials. Incorrect credentials are the most common cause of failed logins.
    • Update your client settings if you have recently changed your passwords.
  2. Multiple Devices with Outdated Credentials

    • If you access your accounts from multiple devices (e.g., computers, phones, tablets), ensure all devices have the correct login credentials.
    • An outdated password saved on any device can trigger the block.
  3. Security Software Interference

    • Check if your security software or firewall is interfering with your client’s connection to the server. Ensure that your clients are allowed to communicate with the server.
  4. Network Issues

    • Network fluctuations can sometimes cause repeated login failures. Restart your router or try accessing your accounts from a different network (e.g., mobile data) to rule out network issues.
  5. Settings Verification

    • Verify that all devices are using the correct settings provided by us, including the correct server addresses and port numbers for the relevant services.
  6. Potential Malware or Viruses

    • Run a thorough malware scan on your devices to ensure there are no malicious programs interfering with your logins.

Identifying the Problem Device

If you have multiple devices accessing your accounts, follow these steps to identify which device might be causing the issue:

  1. Temporary Disconnection: Disconnect all devices from the network except one. Monitor this setup to see if the block occurs again. Gradually reconnect each device one by one, observing if any particular device triggers the block.

  2. Check Recent Activity: Look for any device that might have been recently configured or changed, as it might be causing the issue.

Permanent Blocks

Please note that if your IP address is temporarily blocked more than four times in a single day, it will be permanently blocked (16 failed attempts in the hour X 4). This is to ensure the security and integrity of our server. If your IP is permanently blocked, you will need to contact our support team to resolve the issue.

Temporary Whitelisting

If you experience Permanent Blocks / repeated temporary blocks, we can temporarily whitelist your IP address to prevent it from being blocked again. However, please note that this may reduce the security of your account. If you prefer this option, contact our support team to proceed.
