I just remembered which company did my certification, clicked on the link from ddg and got
Secure Connection Failed
An error occurred during a connection to www.pearsonitcertification.com. Cannot communicate securely with peer: no common encryption algorithm(s).
Error code: SSL_ERROR_NO_CYPHER_OVERLAP
Yeah. Right.

edit: Hm. May have giggled too soon, because https://home.pearsonvue.com/ works. Don't know how the link above is related to them.
