How to make SSL compatible with Video play in Safari

Hello @schoen @sahsanu @jmorahan

I met headache issue with video play only in Safari after SSL setup. Videos play well both in SSL or non-SSL status in Chrome and firefox. I supposed the reason seems related to incorrect intermediate certificates setup, as per at technical topic iphone - Cannot view Quicktime movies over HTTPS in Safari or UIWebView - Stack Overflow

so, I asked an technical to setup new wildcard SSL for our multisite(Payable work for wildcard SSL deploy - #12 by jmorahan), and created a fresh site with no plugin activated, you may find SSL work well:
SSL Checker

Here is my test process:

  1. by default, the site was created https), Screenshot by Lightshot

2.I check the root site, it is still, but not, I just support it is saved in database but I can not change it.

3.if access the subsite: both https or http is accessible ://

4.Upload a standard mp4 video sample downloaded from a professional development site which guarantee the video is support in all of browser,

  1. the default url of the uploaded video is, it is not https, please check the screenshot: Screenshot by Lightshot, and the video is play both frontend and backend, and Here is frontend screenshot: Screenshot by Lightshot

6.Here is screenshot: Screenshot by Lightshot, which show I changed the site url from to

The video URL will automatically change from http to https, here is screenshot: Screenshot by Lightshot

As you see, the video will not play both at backend and frontend, and just show the error as:

Media error: Format(s) not supported or source(s) not

I would like to have your professional suggestion on SSL compatible setting for Safari, how to resolve it please?

Thanks so much.


I would like to see if there is anything difference in the connections themselves…
So, please detail:
On which version(s) of Safari does this occur?
Which TLS protocols/ciphers are the working, and non-working, clients negotiating.

(Let me know if you need any assistance with gathering any of that info.)


Thanks, the version of safari: Version 11.0.3 (12604., screenshot: Screenshot by Lightshot

I knot TLS is something of Handshake Protocol, but I do not know it on my site.

Would like to help? how to resolve please?


Do you have access to modify the vhost config file for:

oh, yes, but I am not technical background, would like to help please?

Hello All,

I am back.

I checked our SSL compatible at


Would you please let me know whether there is any improper setting which might cause the issue of video playing in Safari?


What I’m currently seeing on is a circular redirect, where redirects to itself instead of serving any site content.

Hi @schoen,

Thanks, please check our ssl compatible:

and let check this video page:
or directly this video,

it is uploaded by ftp, and it simple under nginx, so no related to wordpress.

what you think please?

@schoen @rg305,

what is your comment upon our SSL cert compatible:

I would like to check the reason one by one…



Is there any configuration change needed to change to Https in Nginx ?

TLS 1.1 Yes
TLS 1.0 Yes

TLS_RSA_WITH_AES_128_GCM_SHA256 (0x9c)
TLS_RSA_WITH_AES_256_GCM_SHA384 (0x9d)
TLS_RSA_WITH_AES_128_CBC_SHA256 (0x3c)
TLS_RSA_WITH_AES_256_CBC_SHA256 (0x3d)

Strict Transport Security (HSTS)
Supported Named Groups secp256r1 (add more)

Ok, but how to set please???

The simplest and most effective way that I have found is to add “:!SHA1” to the end of your SSLCipherSuite list.
That will remove all the ciphers that end with “_SHA” from the supported list.

do you think those setting is related to video issue please??

I was able to serve your sample video file from another server to a Safari client without any problem.
That same Safari client could not see the that same video from your server.


he reason why I asked this question is that I just read an article which should safari need strictly SSL…

so I just thought if there are different between our SSL and the one of your demo site, that might be a reason…?

or, there is extra configuration needed in Nginx conf, since that video is uploaded to Nginx for test by Ftp, so it is completely no related to wordpress.

I tried it in Apache 2.4.25 and nginx 1.12.2 (both worked with Safari)

so, what is your Nginx conf setting?

both using the default mime.types file
which includes:
nginx =
video/mp4 mp4;

Apache =
video/mp4 mp4 mp4v mpg4
