sending any kind video attachment results in OAuthException: (#389) Unable to fetch video file from URL

[silvermace]

REPRO: run example/server.py - I suspect the FB API has changed in some way as doing a REST call using CURL results in the same error?

• I have checked that the asset URL is reachable by the public internet.
• I have verified the Page Access Token is valid
• I have tried the same REST request using CURL and another python bot framework

I am posting here as fbmq is the best maintained library so thought if there is a workaround or a that a change needs to be made, this is the most likely place it will be posted.
