I am unable to view a video served on localhost:8000 (or 127.0.0.1:8000). I tried the following allowedOrigins: localhost, 127.0.0.1, localhost:8000 and 127.0.0.1:8000.
I get the This video has not been configured to be allowed on this domain error.
Add the port like localhost:666 https://community.cloudflare.com/t/cannot-see-videos-in-localhost/283779/2
