Hi, @ngoclx. I wanted to point out that we can also troubleshoot this privately if you prefer as this is site is part of a Pro level account. Please let us know if this is preferred and I’ll transfer this issue to our support helpdesk.
If you want to troubleshoot this here, we need to be able to track the HTTP response with this issue. One way to do this is to send us the x-nf-request-id header which we send with every HTTP response.
There more information about this header here:
Note, please send the header for the HTTP response which has the issue. For example, if the issue is happening on the video file, please send us the x-nf-request-id header for that response, not for the HTML response.
If that header isn’t available for any reason, please send the information it replaces (or as many of these details as possible). Those details are:
- the complete URL requested
- the IP address for the system making the request
- the IP address for the CDN node that responded
- the day of the request
- the time of the request
- the timezone the time is in
You might also make a HAR file recording of the issue and send that to us as it will normally contain all of the information above.
If there are questions about any of this, please let us know.
