Moving back to server since this is either a nextcloud/server bug or pulsejet/memories bug and not one in nextcloud/all-in-one. Please make sure to also open an issue at pulsejet/memories. |

Bug description
Hello,
when trying to watch a video uploaded by any of my Android devices (Samsung Galaxy S21 FE, Google Pixel 2 XL or Google Pixel 8 Pro (running GrapheneOS)) I'm unable to watch the video. In the overview of Memories and Photos or event the files app I get a preview image. However when clicking on it, I only get sound from the playback but no video. Just a black screen. In addition videos uploaded from an iPhone are playable without any issues.
When doing so I also get an error message in the top right corner telling me to check the protocol because the preview failed. Doing so gives me the following error:
This issue makes it impossible for me to use my Nextcloud for my photo and video backup because it's not really usable if I can't watch the videos I've backed up. I hope there's some fix for that.
I also found some related issues that can maybe help to trace this issue.
In #1475 there was also some solution as it seems to change something up in some PHP file but due to AIO running inside Docker I don't want to fiddle around and change any of the files of Nextcloud inside the Docker installation. My goal is not to break anything and it wouldn't be a reasonable approach for me as an enduser to change something inside the code (as it seems) to try to fix this just on my end.
