What to do if my course is just showing up as a blank black screen?

MichaelRush

I just published a course. Got approved. Went to preview it and shows up as a blank black screen….. I need help resolving this ASAP. Already had a purchase and refund.

Here's the course https://www--udemy--com.udemy.coolkeypoint.com/course/linkedin-mastery-class/.

Contact support at instructorsupport@udemy.com and they will tell you they cannot replicate the issue and it's a problem on your side. I went through this today.

Seriously though send support an email. Perhaps if enough instructors complain this issue will be fixed.

Here is the discussion:

Hello Udemy Support Team,
Previews are not working in courses. This has been going on for some time now. My courses have a lot of preview videos and I would like students to have the option to check them out. Additionally I even considered purchasing a course recently from another instructor however I did not since I could not watch the preview videos so I could not get to see the instructor's pace, teaching style, accent, etc. Too bad, it would be nice if the preview issue would be fixed soon.
Thanks!
Best,Ron

Hi Ron,

Thanks for reaching out.

After checking on our end, we can confirm that the video previewing feature is still working as usual. So we can have a better understanding of the issue, could you provide us with a screen recording of the issue you are seeing?

Thanks for your cooperation and we look forward to your reply.

Kind regards,
Jonas J.

Here is a video demonstrating the issue. I used a link I received from another instructor but the preview does not work. This is an ongoing issue. From my instructor curriculum I can test previews.
In the video I tried this course:

https://www--udemy--com.udemy.coolkeypoint.com/course/learn-threejs-create-a-game-engine-the-jello-city-game/?couponCode=LAUNCH_REDDIT

(In the original email I attached a video demonstrating the issue). Note the above link is not a link to my course, rather a different instructor's course. I wanted to show that it is a general issue and not just mine.

Hi Ron,

Thanks for your reply.

I have attempted to replicate your issue on our end but haven’t been able to, which likely indicates that there is no bug on the Udemy site. You'll likely be able to resolve the issue, however, by trying the steps below:

1. Check your network configuration by clicking here and follow any troubleshooting steps that are recommended.
2. View videos with Auto selected for the resolution. This automatically switches videos to the highest resolution your network can support to provide a smoother streaming experience. Please note this is only available on Chrome & FireFox.
3. Check your internet speed here and attach a screenshot of the results. If your download speed is below 5 Mbps, it means your connection is too slow-- please try connecting to a different network.
4. Access Udemy with an incognito window. If playback improves this indicates an extension on your browser is interfering with your ability to stream.
5. Clear your cache and restart your browser. This often resolves a number of playback issues (without deleting your saved passwords!).
6. If the problem persists please try using a different browser or (if possible) a second device such as your phone. If this fixes your video playback, the issue is connected to the original browser or device you used.

This Help Center article also includes information on how to resolve video viewing issues.

• Does this issue occur on all courses or just a particular course?
• Have you tried restarting your modem?
• Do you have any extensions/plugins/firewall programs running that might be interfering with the video stream?

If you have any further questions, please reach out and we’ll be happy to help you continue troubleshooting!

Kind regards,
Jonas J.

There is no problem on my end. There have been endless complaints on Udemy's community about this issue. Have you looked at the attachment I sent?

or more generally:


This is a real issue. The general feeling in the instructor community is that Udemy has become unreliable and full of bugs.
Best,

Ron
