We have tried using incognito mode, different browsers, and two different computers from two different countries, but unfortunately, the result remains the same.
For one of our websites, we are using a Cloudflare proxy, and to our surprise, we discovered that during an open port scan, port 21 appeared in the scan report. We are curious about why this port 21 is open. Additionally, when scanning from different countries, the reports vary—sometimes it is open, and sometimes not. Could you please explain why this port might be open?
