    A couple of days ago we lost all access to our website. After a DNS refresh mobile devices can access the site as well as any Apple products. Windows devices can not access the site at all. Get err-connect message and also when in incognito mode it says the site doesn’t support HTTPS

    please help

    Thanks

  • I can see your website all right on Windows. Below is a screenshot from Windows 11, Brave (Version 1.73.91 Chromium: 131.0.6778.85) in Incognito mode. I intentionally left the Windows taskbar in there to remove any doubt this screenshot is from Windows.

    I am guessing that you are outside of NY or at the very least Long Island? When using a local ISP Optimum or Verizon it never connects on Windows machines

    Hi @kflorenz,

    How does it behave if you clear the browser cache? You can also verify your DNS settings and HTTPS configuration are correct, and ensure no network restrictions are set by local ISPs.

    You could also check if any antivirus software is blocking access and consider checking on multiple browsers to ensure how it behaves.

    Running a traceroute can help diagnose where the connection fails. Also, would recommend you check on a different Windows PC and with a different internet connection to double-check whether you could replicate the same issue or not.

    If problems persist contacting the ISPs might be better in such instances.

    Kind regards,

    Thank I have done all those things and honestly nothing has worked. It is an issue across all ISPs and only IoS and MacOS are working. It seems as though the website isn’t allowing the connection to serve the data on Windows OS devices only in our region.

    I am truly dumbfounded and have contacted the ISP 4 times and they are stating that nothing is wrong on their side

    PS – I can hit the server and IP without an issue through trace route and such. This is higher up the stack I believe where it’s almost like it won’t allow the socket to connect from the browser on Windows devices

    It sounds like the issue with your website might be related to DNS propagation and SSL certificate compatibility. Here’s a possible explanation and solution:

    DNS Propagation Delay: After a DNS refresh, changes can take up to 48 hours to propagate fully across all networks and devices. Apple devices may have cached the updated DNS, but Windows devices might still be using old DNS data.

    HTTPS/SSL Certificate Issues: The error “site doesn’t support HTTPS” could mean your SSL certificate has expired or isn’t properly configured. Mobile devices sometimes handle SSL errors differently than desktop browsers, which is why Apple devices might still access the site.

    Solution:

    Clear DNS Cache on Windows devices (ipconfig /flushdns via Command Prompt).
    Check the SSL Certificate using an online tool like SSL Labs.
    Reconfigure HTTPS settings on the server and ensure the certificate is valid and up-to-date.
    Check DNS Settings for any misconfigurations. Read It For More Information

    I want to thank everyone for all the help. We found the issue to be the SSL certificate. I had decided to swap it out and once it was changed and applied with the old one removed everything came back within 20 min and all devices are now connecting successfully. I appreciate you all!
