### Actual Behavior

### Screenshots

### Additional Information

Keeping the F12 console open when launching the video player shows `https://yleawsmpondemand-03.akamaized.net/vod/finland/846acc3fe30a48ffaaa96cdf5a2798c5/a8f702fdc8e7449cae194919044a34ee/d5fb3a697dbb4efda98a6aea7cb21fe7/index.m3u8?hdnts=exp=1747062081~acl=/vod/finland/846acc3fe30a48ffaaa96cdf5a2798c5/a8f702fdc8e7449cae194919044a34ee/*~hmac=afef4ced8776c16308cb2869db6b98d0b4203213869a2d5307a41825a0b8810e` with a HTML 403 (Forbidden) error code, so it may plausibly be that it's Akamaized that needs to be fixed for that Helsinki server.

For testers who are more comfortable with Finnish text than Swedish, the URL in step 2 can be substituted by `https://areena.yle.fi/1-68185857` instead.
