This is probably a duplicate of #7069

[jomat]

No.
I have the images issue sometimes on slow connections.

But I wasn't able to upload small videos (see the size in the screenshot!) for a year or so. And my private internet connection has 50 mbps upstream. And other users are also complaining about this issue alot!

Feel free to try it yourself before closing this issue. Both, Riot and HS registration are publicly available.

Found and resolved the problem, wasn't related to #7069. Also solved another problem which looked like #11418 despite it affected all videos (again) and thus didn't have the same causes probably. I didn't open an issue as it would have been closed as duplicate anyways :-(

Both problems were my fault and not caused by riot, no further action needed.

can you say what the fault was on your side, in case others make the same mistake? (to avoid https://xkcd.com/979/)

@ara4n it was a CSP misconfiguration
