    Hello!

    After creating the site and setting it all up , sometimes it takes a few minutes to populate throughout our network.

    At the time of writing this, the test URL currently works for me :

    https://wwf1uz2ok3e3.cdn.shift8web.com/wp-content/plugins/shift8-cdn/test/test.png

    I will close this issue for now but feel free to update again if you still have issues.

    Thanks!

    Hello,

    I looked into this further and it looks like one of our endpoint servers (that is probably geographically busiest for you) is being blocked from communicating to your website.

    # curl -X HEAD -i https://www.conceptualise.in/wp-content/plugins/shift8-cdn/test/test.png
curl: (7) Failed connect to www.conceptualise.in:443; Connection timed out

    I’ve seen this happen sometimes with shared web hosting providers. They think traffic from our CDN is artificial or malicious where instead we are just making a lot of requests to fetch content, especially if a site is busy.

    If the web host has a security system where it blocks requests that exceed a threshold, then it will make the CDN appear to not function anymore. You need to check with your web host if they can adjust that threshold to accommodate our CDN.

    You can also give them a list of IP addresses to whitelist , if they prefer. To get the IP address list of our endpoints you can send an email to [email protected]

    Thank you!
