All embeds say 'this track is currently not available'

Hello, I’ve used the Soundcloud shortcode plugin for a while and never had no problems embedding songs onto articles before but just recently everytime I use it it just comes up with the player saying ‘this track is currently not available’.

My site is https://www.rootsounds.co.uk and its a local music website so the plugin is brilliant to use for the site. It would be great if this could be ironed out as otherwise I am going to have to look for another plugin and then edit every article on the site.

Cheers

Shaun
