I can't upload a video.

Occasional Contributor



I can't upload any video of any size. The upload 'circle' goes round and then eventually fails. However, I can upload the same videos to Microsoft Video.


This is a sudden thing asI have previously been able to upload videos on Stream.


Any help would be wonderful.

We are having the same problem; did you manage to get yours resolved? We are currently looking at migrating from Office 365 Video to Stream but the process has not been smooth. Will be creating a support ticket shortly.

If you don't have the ability to specify wildcards then you will be needing to include


and everything inbetween. 001,002,003 etc.


I did however also whitelist the following for good measure;



Hope this helps someone in the future. Videos are now successfully uploading.

Glad you got it figured out.


FYI... We have all the URLs you need to whitelist / allow within your network here.


(It's a combined list between O365 Video/Stream. Not all the URLs are used by both services).

Brilliant! That is very useful, thank you for providing the link, much appreciated.
