@gracjan this does sound a bit like an issue on the instances side. I did implement a fairly restrictive request limit on the webserver side when I implemented IP cloaking which should be JUST enough for typical use cases. But maybe Mona does an untypically amount of requests, or you are just a power user :eichkatzo:. Please try to browse https://ieji.de on the device next time you get these issues that the media couldn't be loaded. If it shows "Forbidden" it's the limit you are hitting.
