Website doesn't load videos

Hi,
long time user here!
in the latest weeks when I try to watch a video it won't load. I tried with Firefox and Brave on desktop (adblock disabled) and samsung browser on mobile.
The page is stuck like that for 5 minutes:

<img width="2058" height="1594" alt="Image" src="https://github.com/user-attachments/assets/a1b96218-f1b7-490c-b1ec-31e986f0c8b8" />

There is anything that I can do?
