@squareclouds Most likely, this is not related to PHP version. But related to CSP or CORS configuration.
-
CSP (Content Security Policy) is set via a header and tells the browser what content is allowed/trusted by your web page. By default, Cloudron does not set any CSP header but you can override it . If your app has a CSP, then it can disable "embedding" of content . For example, youtube/tiktok videos etc can be prevented from being embedded.
-
CORS (Cross origin resource sharing) is set via headers. This tells the browser if ajax calls are allowed from another origin. Cloudron does not set CORS headers either. This means that "random.site.com" cannot call your "dev.mydomain.de" . This is good (tm).
OK, so, with this in mind and trying to understand your error:
Blocked a frame with origin "https://www.tiktok.com" from accessing a frame with origin "https://dev.mydomain.de".This tells me that the tiktok frame is trying to access your domain. Is this understanding correct? Why is tiktok calling your domain? Maybe it's trying to report back something to the parent domain ? Is this just some random tiktok video? -

thank you for the reply. yes i think this is going in the right direction. i already tried the CSP, just to see what happens i tried something like default-src * and scripts and other things, but it didnt work, so i think its CORS. that i didnt know how to test with different settings. do you have any suggestions of what i could test?
regarding your question, well i guess Im not sure why it tries to access or what or if that indeed is the case. all other browsers (mainly non apple) aren not having problems or the regular hosting servers even with everything thats apple, as i mentioned, so it is a bit confusing.
-
@squareclouds do you have a barebones html to help reproduce the issue on the LAMP app? So, just embedding a tiktok video in a simple html page and hosting it on the LAMP app will reproduce the issue?
-
@girish good point! i just tried it, yes, it does not work. this link i can share with you
-
@squareclouds seems to work for me here:
Do you maybe have some privacy plugins installed in your browser which might interfere here?
-
@squareclouds loads for me too on Chrome/Linux.
On firefox, only some text shows up. The console says some 'content blocking is enabled' . If i click on the shield icon on the URL bar and disable "Enhanced tracking protection" , it loads for me on Firefox/Linux also.
But I think you said this is only an issue on iphone/mac is it?
-
thank you both for your tests. yes, again, the behaviour is:
- Tiktok embeds are not being autoplayed on macOS Safari nor any iOS browser
- Not only they dont autoplay, but they cannot be played even with user interaction
all other browsers on macOS work fine. BUT dont forget that all of the above works fine on other servers! so it cannot be a browser setting, if the embeds of the same website project work on the other non-cloudron servers
it is a bit hard to follow, i know. -
@squareclouds I don't have access to any apple devices to test and debug this on my own.
-
@nebulon luckily it is a feature that is partially critical. we dont know how many users will be embeding tiktoks, and from those embeds only the ones visited by users on iOS or safari on mac will have the issue. but i am pretty sure its gonna be some very small setting or adjustment somewhere to fix this, we must only figure out where
can one of you point me in the direction of how to set a CORS setting on cloudron? i have no clue about such things but if i play around a bit i might find a solution by chance.
-
@squareclouds CORS related settings would need to be adjusted in the remote server, not the one hosting it. So I don't think this is viable here nor is likely the main issue.
For CSP you can overwrite the headers at https://docs.cloudron.io/apps/#custom-csp or also via meta tags in the html directly. See https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Content-Security-Policy

@girish said in Cloudron+LAMP: Tiktok Embed problems:
@squareclouds Most likely, this is not related to PHP version. But related to CSP or CORS configuration.

This tells me that the tiktok frame is trying to access your domain. Is this understanding correct? Why is tiktok calling your domain? Maybe it's trying to report back something to the parent domain ? Is this just some random tiktok video?
but it seems that there is a call from tiktok to our server, which would mean that our server needs the cors, or not?
-
@squareclouds I don't think tiktok will call your server, anyways there is no service besides apache running to call into.
-
@nebulon random guess - TikTok is doing some Postmessage to parent frame which is getting blocked. This is what I inferred from the original error that @squareclouds posted.
I might get access to a Mac later today, i will try. Very intriguing.
-
@girish thank you dear sir. yes, its strange ^^ crossing fingers that you find out something when you have the chance.
-
@squareclouds I tried the site on Mac Ventura with Firefox, Chrome and Safari. It all loads fine.
Also loads fine on an iphone with safari/chrome . So, I am yet to see this fail anywhere.
Did you get reports from all iphone/mac users that the site does not load?
-
@girish you can play the embed? because it loads, yes, but the playing is the problem. it does not autoplay nor you can play it by clicking it, it has no interaction
we are still not live, so we are only a few people, but yes, its not only on my macs and iphones (i have an old iphone and old mac as well, so me alone have tested on 4 devices and then the lead designer as well).
-
@squareclouds I can confirm this on latest iOS. Sitting in a train and can not further investigate.
The play button is rendered but is not clickable while the buttons on the right all link to TikTok (as they should)
-
@jaschaezra thanks for testing.
@squareclouds ok, we can reproduce this too . Looks like a Safari specific issue. Mac/Firefox and Mac/Chrome plays fine (can you confirm this?)
In https://www.buzzfeed.com/buzzfeedstaff/how-to-get-tiktoks-to-play and https://florisdeleeuwnl.zendesk.com/hc/en-us/articles/360013564340-Embedded-video-not-working-in-Safari , they suggest unchecking "Prevent Cross-Site Tracking" but atleast here that doesn't help.
-
@squareclouds do you happen to have your website hosting link with the tiktok embed? No idea what's going on at this point. We have to compare what is working and what is not.
-
@girish yes, I confirm that on mac only safari has this issue, on iOS it is all browsers (maybe because they have to go through the app store?)
hmm, sure, technically I shouldn't share it but since it is for its own sake:
again, I think we were close already with the CORS, because tiktok tries to reach to the website from the iframe. is there a way that I can explicitly allow it to see what happens?
