You’ll need to send a support ticket if you need assistance debugging. We do not do that in the forums. Thanks.
I can get thumbnails according to wowza document https://www.wowza.com/docs/how-to-generate-thumbnail-images-of-live-streams, but I can’t use ‘test’ instance. Why
We’re not sure and is not possible to determine through the forums unfortunately. Can you send in a support ticket and we’ll be able to debug the issue there. Thanks.
