Unable to get my front end development certificate from my portfolio page

I have completed all my challenges and have successfully claimed my front end certificate. But I cant find it anywhere, not on my profile, my portfolio page, it is nowhere to be found!! How do I go around this. I used this link (https://www.freecodecamp.org/Diboku/front-end-certification) yet it kept telling me that there is no user with my username. Please it is frustrating.

Can you log into your freeCodeCamp account, click settings > view public profile then share the URL for your user profile?
