I'm seeing someone a year ago in a comment wrote he had a similar problem. I quote:
"No offense, but something is definitely broken (probably your file streaming). The file seems to work now since my original post. I write software for a living, so I'm not some casual computer user. I download huge files all the time from other sources and I never have any issues. You have lots of files on this site that don't download properly and/or play properly. See the comment below from notoriousLRG who can confirm this same issue. There are also LOTS of comments on other videos about certain formats not downloading and/or playing properly. Rather than blaming the customer by appealing to your 1000s of customers who may or may not be complaining -- or even downloading the same formats, try investigating the actual problem. I would encourage you to actually download the file from your site as a customer would before testing it (in case you are trying to test the copy you have on your servers directly). Also I would encourage you to download the file from outside your network (remotely again like a customer would). I would also run simultaneous downloads to see if this is a factor.
The list of issues I have continually encountered on this site:
1) File downloads just canceling with no error explanation, but work on retry (constant issue)
2) Files that seem to download but are corrupt and won't play at all
3) Files that seem to download but you don't get the whole file (may be the same as the second issue, but may depend how much of the file you actually get). Even when downloading the file multiple times, it will cut off at the exact same point.
I can replicate these issues both on my desktop and my quest 2 device. It's hard to argue it's on my end when the quest 2 hardware is the same for everyone. I honestly think if your file streaming that doesn't work properly. Perhaps it's intermittent and only happens with heavy server load, which may be another reason why you can't replicate it or why it may work for some customer and not others." - https://www.sexlikereal.com/scenes/see-what-im-seeing-25344?tab=downloads
