    If I understand correctly, you're facing an issue where one website goes down and another website automatically comes up on the same ports (80 and 443). There could be a few possible explanations for this situation:

    1. Load balancing: It's possible that you have implemented a load balancings solution, such as a reverse proxy or a load balancer, that distributes incoming traffic across multiple servers hosting different websites. When one website goes down, the load balancer detects the failure and redirects traffic to a healthy website.

    DNS configuration: The DNS (Domain Name System) configuration for your domain names may be set up in such a way that when one website is unreachable, the DNS automatically points to an alternative IP address hosting a different website. This can be achieved through techniques like DNS failover or round-robin DNS.

    1. Virtual hosting: If you are using a web server that supports virtual hosting, such as Apache or Nginx, it's possible to configure multiple websites to share the same IP address and ports (80 and 443). In this case, when one website goes down, the web server may serve as a default or fallback website instead.
    2. Script or automation: There could be a script or automation process running on your server that monitors the availability of websites. When it detects that a website is down, it automatically starts another website on the same ports to ensure continuity of service.

    To identify the specific cause of this behavior, you'll need to examine your server configuration, load balancer settings, DNS records, and any automation scripts that may be involved. Consulting with a system administrator or a web developer experienced in server management can be helpful in diagnosing and resolving the issue.

    The same problem I was facing in my website conversioncalculator But the problem is solved after tried this solution

    To troubleshoot and resolve the issue of one website automatically going down and another website coming up on the same ports (80, 443), you can follow these steps:

    Check server logs: Examine the server logs of the website that is going down to identify any errors or issues that may be causing it to become unresponsive. Look for any relevant error messages or indications of a problem.

    Verify network connectivity: Ensure that the server hosting the websites has stable and uninterrupted network connectivity. Check for any network issues or firewall configurations that may be blocking incoming traffic.

    Review server configuration: Verify the configuration of your web server (e.g., Apache, Nginx) to ensure that multiple websites are set up correctly. Check for any misconfigurations or conflicts in virtual host settings that may cause one website to go down and another to come up.

    Check load balancing setup: If you have implemented a load balancing solution, review its configuration to ensure it is working as intended. Check the health checks, load balancing algorithm, and failover settings to see if they are appropriately configured.

    Examine DNS configuration: Inspect the DNS settings for your domain names. Ensure that the DNS records are correctly configured and pointing to the intended IP addresses for each website. Check if any DNS failover or round-robin configurations are in place that may be affecting the behavior.

    Investigate automation scripts: If you have any automation scripts or processes monitoring website availability, review their configurations and logic. Check if there are any scripts that automatically start a different website when one goes down.

    Test website independently: Conduct individual tests on each website hosted on the server to determine if there are any specific issues with a particular website's code, database, or dependencies. This will help identify any website-specific problems that may be causing the downtime.

    Seek professional assistance: If you are unable to identify or resolve the issue on your own, consider consulting with a system administrator, web developer, or a hosting provider's support team for further assistance. They can provide expert guidance and help resolve the problem.

    Remember to document any changes you make during the troubleshooting process and proceed with caution to avoid causing further disruptions.

    So exactly how many milligrams are there in a milliliter? The first step to answering this question is to understand what the letter 'm' means when applied to units. It means one-thousandth (1/1000) of the original unit. Therefore we're asking how many thousandths of a gram are there in a thousandth of a liter. Recall that a gram is one-thousandth of a kilogram. If you need help converting weight from a different unit to mg, our weight converter can help. here how to convert mg to ml calculator

    Now that we've sorted that out, the question is now "What is the relationship between kilograms and liters?"

    The kilogram was originally defined in 1795 as equal to one liter of water at the temperature of melting ice (0 °C / 32 °F). That's not entirely true in the present day, as the kilogram and meter (a liter is the volume of one-thousandths of a cubic meter) have been re-defined, but it's very close indeed (0.9998 kg is a more precise figure).

    So, a milligram is a thousandth of a thousandth of a kilogram, and a milliliter is a thousandth of a liter. Notice there is an extra thousandth on the weight unit. Therefore, there must be 1,000 milligrams in a milliliter, making the formula for mg to ml conversion:

    mL = mg / 1000.
