SAP Learning exercises not loading – certificate error NET::ERR_CERT_DATE_INVALID

Hello SAP Community, I am facing an issue when trying to launch exercises from SAP Learning. When I click any exercise link, a new tab opens but the page is blocked with the following error: “Your connection is not private – NET::ERR_CERT_DATE_INVALID” The domain affected is: education.hana.ondemand.com

Troubleshooting already done:

Tested on Edge and Chrome
Cleared browser cache
Tried from another device
Tried from mobile network (not Wi‑Fi) → The same error appears everywhere.

This looks like an expired or invalid certificate on the SAP Learning environment. Is anyone else experiencing this issue? Is there an official update or workaround?

Thank you in advance.

Aurelia
