WordPress: Streaming is breaking for some users on Safari

[Patrick]

I’m getting support notices from members using Mac OS 10.11, 10.12, 10.14 with Safari 12.x…

Here’s what one member is complaining about (that matches other reports):

I am using Safari browser on Mac OS Mojave 10.14.2 and I keep getting playback issues after 1 minute that says there is an issue. After I refresh the page, I can click play, scrub back to where I left off and it will play for 1 minute and the error happens again. Its happening no matter where I scrub to and have opened several other tutorial videos and they also encounter the same error message. In the mean time, I am using Google Chrome browser but just thought I would bring to your attention in case anyone else is encountering this as well.

Here’s a screenshot that another member grabbed for us:

Our first report of this error was about three weeks ago. We’ve had several this week. Some members never even get playback to happen – they press play and immediately get the error message.

The workaround is to switch to Chrome. Obviously, that’s not a long term solution since this problem is also effecting Safari on iOS.

Unfortunately – I’ve been unable to replicate this problem. I’ve invalidated the caches for the Cloudfront distribution we use – but reports are coming in even after that.

Please advise.

You can test one of our streams here:

We found the cause of this streaming problem. We needed to exclude caching of the S3Bubble plug-in folder of our WordPress install. This immediately fixed the problem.

We still have a problem with iOS streaming using Media Convert. But that’s another thread.
