Hi there,  
I installed an own mattermost-server and love it.  
One day ago the link-preview stoped working on browser and win-app for all users. It still workes fine on mobile. I did not change anything.  
Can you help me restoring it?  
Greetings from Germany

Hello @NebuKadneZaar, I’m sorry to hear that you’re having issues, I do believe we’ll be able to solve this though!

Are you seeing any error messages in your Mattermost logs? It may help to change the Mattermost logging level to `DEBUG` and then replicate the issue.

Hi @XxLilBoPeepsxX,  
thx for your help!  
The Log doesnt show in the browser-version or the windows-app.  
But I can write an email to the support with my mobile-app. It shows the log too.

Hello, @NebuKadneZaar

Just to confirm that you have the following feature is enabled on the desktop / web app:

 ![image](https://us1.discourse-cdn.com/flex020/uploads/mattermost/original/2X/9/988e858c40dab177a88c356845189e56d19f35a3.png)

Since you mentioned that it works on the mobile app and assuming that [Link Preview](https://docs.mattermost.com/administration/config-settings.html#enable-link-previews) is enabled, this would be the first thing that I will look at.

Hi, @NebuKadneZaar

Got it. I would like to reproduce it on my end to verify the behavior to see if it is a misconfiguration or otherwise. Can you confirm on the following:

- Windows OS version
- Mattermost Server version
- Mattermost Windows app version
- Web browser version
- Sample YouTube URLs and other sites which are not working for you

You mentioned that it worked for some sites. Can you share the links here please?

I do wonder if it is possible that a website that doesn’t have meta tags such as the following would not have a URL preview because of the lack of meta content to be served in the preview. See below for example of meta content, which is what is shown in URL previews.

```auto
<meta property="og:title" content="Example Domain">
<meta property="og:type" content="website">
<meta property="og:description" content="Welcome to example.com, the number one website on the internet!">
<meta name="theme-color" content="#478ac9">
<link rel="canonical" href="https://example.com">
<meta property="og:url" content="index.html">

```

I am not sure if this applies here because Youtube and Amazon provide those meta tags, dont they?

This seems to be on Youtube’s end, please see details here [https://github.com/mattermost/mattermost-server/issues/16429#issuecomment-741823889](https://github.com/mattermost/mattermost-server/issues/16429#issuecomment-741823889).

I’d also like to note that for YouTube scraping and loading, your supposed to have a Google API key in your configuration (and if that isn’t still a part of the Mattermost setup, it is required by Google to scrape and fetch from their platforms)

Yeah I have an API Key configured.

Fun fact: Youtube preview worked on on vid on thursday. Could be reproduced on thursday.  
Doesnt work anymore right now.

By any chance, do you have any specific CORS policies enabled, or same-site script-security measures enabled that are different from the configuration explicitly mentioned by the Mattermost install documentation?

In your `config.json` file, is `'EnableLinkPreviews": true` set to true?
