Video Upload failes because of Access-Control-Allow-Origin on Safari


Hi there,

I encountered an upload issue on my Edit Activity page when trying to add a video to my activity. See screenshot below. I’m happy to share the HAR file of that request and the detailed URL on a private channel. The issue is repeatable. OS: MacOS 15.3.2 (24D81) / Safari: Version 18.3.1 (20620.2.4.11.6).

Let me know if you need anything else.

I have the same problem with firefox/librewolf.

Also video-upload isn’t working anymore with the strava-app.

Video uploads aren’t working for me at all (Firefox on Windows). Just getting the spinning uploading circle on the edit page, I don’t get any errors or timeout, it just never appears to upload. This has been happening for at least 3 days now. ​@support any information on this, it seems like it’s not just me?

Edit: yes, I’ve cleared cache/cookies, tried another browser (Edge 💀), and tried different video clips.
