-Clear your cache and attempt to watch it again? -Log into your HubSpot course from an incognito browser, or attempt it on another network? -If you're still having an issue, please submit a HAR file to me and let me know what course you're trying to take (if you message me, I can provide you an email to send it to)
A HAR file is essentially a recording of you doing the action that is resulting in an error so we can take a look at it more closely to figure out what's going on. Here is a link with instructions on how to collect a HAR, and below are the instructions (If you need instructions for a different web browser, please visit the link). When you're done, save the file and send it back to me. Let me know if the file is too large for you to attach to this ticket.
These steps are specific to Google Chrome, which is available for download here.
Open the Developer Tools from the menu (Menu > More Tools > Developer tools), or by pressing F12 (or Fn-F12) on your keyboard.
Click on the Network tab
Look for a round button at the top left of the Network tab. Make sure it's red. If it's grey, click it once to start recording.
Turn on "Preserve log".
You can use the clear button (a circle with a diagonal line through it) right before trying to reproduce the issue to remove unnecessary header information.
Reproduce the issue.
Save the capture by right-clicking on the grid and choosing "Save as HAR with Content".
Save the file to the desired location on your computer and then attach it to your Support ticket, or email it to me if the file is too large.
