Why is Publer not generating a link preview?
Sometimes certain links will not work properly and Publer will not be able to generate the preview of those links.
If your website is not allowing it due to hot-linking issues, it will look like the image below:

You have to turn-off/disable image hot-linking protection.
To turn-off or disable hot-lining for Publer, you can follow this guide here.
Alternatively, you have to whitelist the "publer.io" domain.
Keep in mind that not seeing the link preview won't cause any issues when posting to social networks. The only issue is that you can't visualize the preview in Publer.
If there are no proper OG Image Meta Tags, it will look like the image below:

Open Graph meta tags are snippets of code that control how URLs are displayed when shared on social media.
They’re part of the Open Graph protocol and are used by many social media sites, such as Facebook, LinkedIn, and Twitter.
You can find them in the <head> section of a webpage. Any tags with "og:" before a property name are Open Graph tags.
