DNS Issues - Not being able to access university websites outside UK

Hello,
 
I am having issues to enter 2 different university websites that are from Argentina:
      udemm.edu.ar
      uade.edu.ar

The error I'm getting is: This site can’t be reached: udemm.edu.ar took too long to respond.

This is happening only with my Plusnet connection. However, I'm able to access with my cellphone data, and also a friend with another ISP can access these pages.

Things I've tried:
  - Used a public DNS like Google DNS
  - Tried multiple browsers and different OS. Clear cache also.
  - Ran flush dns commands
  - Ran traceroute and got timeout on certain IP (I can give more info if needed)

If anyone can help it would be amazing!!

Thanks in advance.
