Video is not visible only audio is playing. screen is black

When trying to play a video in Lumi, the audio plays normally, but the video/visual content does not appear. The screen remains blank/frozen while the audio continues to play.

BLACK SCREEN

I am experiencing a problem with YouTube videos when using the H5P Interactive Video content type in Lumi. The issue started suddenly today. The exact same YouTube videos were working normally yesterday, but now the video area appears completely black. The important details are: The YouTube video loads and plays. The audio works normally. The H5P interactions also work normally at the correct timestamps. However, the video image remains completely black during playback. The video duration is detected correctly. The same problem happens with different YouTube videos, not only one specific video. The YouTube videos themselves work perfectly when opened directly on YouTube; both video and audio are displayed normally. If I upload the original MP4 file directly from my computer into Lumi instead of using a YouTube URL, the video image displays correctly. Therefore, the problem seems specifically related to YouTube video embedding/playback inside H5P Interactive Video. I also exported one of the affected projects as an.h5p file and uploaded it to my MoodleCloud course. The exact same issue occurs there: audio works, H5P interactions work, but the YouTube video image is black. Even H5P activities that I created and uploaded yesterday, which were working correctly at that time, are now showing the same black screen in Moodle. I have already tried the following troubleshooting steps: Restarted the computer. Tried Microsoft Edge. Tried Google Chrome. Created a new Lumi account. Created a completely new H5P Interactive Video project. Tested a different YouTube video URL. Tested older H5P projects that previously worked. Tested the YouTube video directly on YouTube, where it works normally. Tested uploading the MP4 file directly into Lumi, where it also works normally. I also received an “Internal Error” message from Lumi shortly before this problem started. Because the same issue occurs with multiple YouTube links, multiple browsers, a new Lumi account, and also after exporting the H5P file to Moodle, it appears that there may currently be an issue with YouTube playback or embedding inside H5P Interactive Video. This is very important for my project because I am using YouTube as the video source to keep the H5P files small and avoid consuming a large amount of MoodleCloud storage. Could you please let me know: Is this a known issue currently affecting Lumi or H5P Interactive Video? Is there a temporary workaround that still allows us to use YouTube URLs? Is an update or fix currently being prepared? Will existing H5P projects automatically work again once the issue is fixed, or will they need to be recreated or re-saved?

Login Problem and Errors in Deployed Videos

I can’t log in, and the shareable links are also not working because the Lumi server appears to be down.

Black screen with sound

For the past three days, the videos I’ve been uploading to YouTube and linking to in the Lumi Editor haven’t been working properly. There’s no sound, and the screen is black. This issue has also affected all the videos I uploaded to my free website, where I share videos with my students. What can I do to fix this problem? Thank you for any advice.

Video is not playing only audio is playing

When trying to play a video in Lumi, the audio plays normally, but the video/visual content does not appear. The screen remains blank/frozen while the audio continues to play.

I have logged into my account just now and found all my video footage from in my deployments is missing. I can hear the audio but the screen is black. This is a critical issue for me.

Won't let me login. Says login successful then goes back to login page.

Deploy Feature not working

When you click deploy on either of the two ways, genuinely nothing happens. The button reacts like you are pressing it with the reactive press icon but genuinely nothing happens. The console also shows nothing happening when the button is clicked. Please, I need these deployments online ASAP!

Update H5P.Core to v1.28

Upgrade H5P.Core to version 1.28 to restore compatibility with H5P.com and ensure smoother interoperability between platforms. This update will align Lumi with the current H5P standard, reduce integration issues, and improve reliability when importing, exporting, or sharing content. The goal is to maintain compatibility with the wider H5P ecosystem and keep the platform technically up to date.

Downloads bug

The downloads are getting stuck in waiting. They have been stuck for a couple of days. There is no way to clear them out. I already cleared out browser cache, and I am uploading my videos through youtube to reduce size of file. It seems like a platform issue. If possible creating a button to clear out downloads would be a great add-on.

Unable to receive password reset email for Lumi.education account

The customer is reporting an issue with password reset for their Lumi.education account. They utilized the 'Forgot your password?' option on the login page and entered their email address, but have not received the password reset email. The customer has confirmed checking their spam folder without success. They require manual assistance from the support team as the automated password reset process is not functioning.

Unable to Set Password for Google-Linked Account

Customer, who signed up using Google, is unable to establish a password for their account. They attempted to change their username but were prompted for a 'current password' which they do not possess. The customer then tried the 'Forgot Password' flow. They reported that the 'Reset Password' button on the website is unresponsive, and no password reset emails are being received in their inbox, spam, or other folders, despite checking thoroughly. They have tried this in Chrome and also in an Incognito window, but the issue persists. The system indicates that because the account was created via Google Sign-in, there is no local password to reset, requiring manual intervention from the support team to initialize a password or update the username.
