Hello stefan van leeuwen,
Thank you for posting in Q&A forum.
After open the link you mentioned, after a while, I will see the error below.
I can also see:
This renewal assessment and the related certification are retired. Learn more.
After clicking Learn More, I can see:
https://learn.microsoft.com/en-us/credentials/certifications/renew-your-microsoft-certification
You can click "Check my eligibility in profile" and check if you can renew your certificates.
You can click "About certification renewal" to check more information.
I hope the information above is helpful.
If you have any questions or concerns, please feel free to let us know.
Best Regards,
Daisy Zhou
