Troubleshooting Guide?

Hello, I’ve been using this plugin for a couple of weeks and as of yesterday it has stopped working but I do not know why. I have deactivated-reactivated and uninstalled-reinstalled the plugin (WP 5.5.1) but it remains non-functional.

As of yesterday all links added are displayed as the shortcode [beautiful_link_preview url=”https://url.tls”%5D but no preview is generated. Likewise the target page is not fetched and included in the “link previews” tab within the plug-in settings.

Links added via shortcode prior to yesterday keep displaying correctly (and are correctly logged in the “link previews” tab).
