403 error when trying to add IMDb link to LinkedIN

​ I'm trying to add a link to my IMDb page in the "featured" section in LinkedIn and I'm getting the error: "Sorry, we were unable to retrieve information about your link. Please try another link."​

​LinkedIN support says: check this link in "LinkedIN Post Inspector" and it shows "403 error" on every IMDb page.​

​Here is example: ​​https://www.linkedin.com/post-inspector/inspect/imdb.com​

​Also LinkedIN support says that problem is not on their side so I decided to contact IMDb support.​

​ ​​ ​

​Maybe you know how to fix this issue.​
​Thanks! ​
