将显示Amazon S3错误防火墙临时标头

Question

I am having a issue regarding Amazon S3 urls giving the error

Provisional headers are shown

I only seem to get this error when i am connected to the wifi over certain networks my main problem is when i am in starbucks on their WIFI i get the error but on any other WIFI i dont get the error and the video will play fine.

I am using the latest Amazon PHP SDK to provide signed urls like below.

$url = $client->getObjectUrl('videos', 'movie.mp4', '+59 minutes', array(
                            'ResponseContentType' => 'video/mp4'
                        ));

This will generate me a signed url like this.

https://video.s3.amazonaws.com/movie.mp4?response-content-type=video%2Fmp4&AWSAccessKeyId=AKIAJHLH6A2TDNLM37YQ&Expires=1409164722&Signature=melsHcsVaXRONs72dhNqM407Cnc%3D

Below is the working version which has a content range bytes

    Accept-Ranges:bytes
    Content-Length:141956
    Content-Range:bytes 9223221-9365176/9365177
    Content-Type:video/mp4

But when i am on starbucks WIFI i get the error.

Provisional headers are shown

But no bytes range 0-

I know this is vague question and someone will probably instantly down vote it but it is a genuine issue i am experiencing and i really need to get it resolved.

It means anyone watching videos on my website wont be able to view them over certain WIFI connections normally public ones all i can think is it maybe a firewall error.

Any help please or suggestions

Answer 1

My first guess it that there is no error, and StarBucks has just decided to block that traffic for whatever reason their firewall deemed fit.

Provisional headers returned seems to indicate that a request was blocked. More info about that can be found here. "CAUTION: provisional headers are shown" in Chrome debugger
