link featured image gets broken

Hi there! On many posts initially it seems that importing a roalty free image works, but many times the link to the url is broken: example: https://topcoaches.eu/7-wijze-lessen-over-innovatieve-ambulante-ggz-in-de-wijk/ featured image: https://www.screencast.com/t/1ghO5cQiNw link featured image: (h)ttps://topcoaches.eu/wp-content/uploads/2021/06/4662-7-wijze-lessen-over-innovatieve-ambulante-ggz-in-de-wijk.png Do you have any clue why the url gets broken? regards
