Trouble autheticating LinkedIn account

Hello - I have recently faced the issue when using Recruit that it will not authenticate me. When I click on a LI icon I get the message:

You need to authenticate yourself with your LinkedIn account to use this feature.

I have used this function extensively in the past but recently it started refusing to authenticate my Linked In account. When I go to Settings > Social Network Integration > Connect to LinkedIn - I get the following message in a pop up window.

"Some error occured in authenticating your LinkedIn account. Click hereto close the popup."

I have recently changed my name on LinkedIn (but not my email or any other identifying information). I have also cleared my browser history, cache etc and ensured that the browser setting allows pop ups but it still doesn't work.

Any suggestions to get it to work?

Thank you.
