  • Issue: After adding an entry to the list of prepopulation tasks, the entry is still in the Configured state.

    Cause: A prepopulation task takes approximately one minute move to the Downloading state.

    Resolution: Check the status of the entry after a minute or refresh the page to verify that the status changes to Downloading.

  • Issue: After adding an entry to the list of prepopulation tasks, the status of the entry displays ERROR 403. However, the website works fine in a Web browser.

    Cause: The IP address of the Citrix SD-WAN WANOP apA does not have access to the video server.

    Resolution: To resolve this issue, verify and update the following:

    • Access rules across the firewalls

    • Source IP address based limitations in the httpd.conf file of the video server

    Cause: The video server does not support the HEAD method.

    Resolution: The video server must permit Citrix SD-WAN WANOP IP address for this method.

    Cause: Directory listing for folders is not enabled on the video server.

    Resolution: The video server must enable directory listing for the folders.

  • Issue: After creating entries for prepopulation tasks, you cannot modify or delete entries.

    Cause: You might have clicked Start Now for the entry.

    Resolution: This is by design. You cannot modify or delete an entry after you have clicked Start Now for the entry and the entry is in the queued, starting, or downloading state. You can delete the entry only after the download is complete.

  • Issue: After creating entries for propopulation tasks, video is not getting downloaded and cached. The status of the entry displays Failed to Download.

    Cause: The prepopulation entry does not have absolute URL for the video.

    Resolution: To resolve this issue, complete the following procedure:

    1. Verify that the prepopulation entry has the actual URL of the video, such as http://10.102.29.16/Citrix SD-WAN WANOP\_demo.mp4, and not an HTML file. The Citrix SD-WAN WANOP appliance cannot search the content of the HTML file to find the video link.

    2. Verify that the HTTP protocol is used to serve the video. You can verify this by using the View Source option of the web browser.

    3. You can get the absolute URL of the video by using the Developer Tools option of the web browser.
