Report says "You do not have a secure HTTPS server" even though I have a valid SSL certificate

[dave0688]

Hi,

I want to package my PWA, and also the service worker is found.
Please look at my report card here:
https://www.pwabuilder.com/reportcard?site=https://dev.app.leafconnect.de/pwa

However, after a while it says "You do not have a secure HTTPS server". But my website has a valid certificate.

Just for explanation:
The url is https://dev.app.leafconnect.de/pwa (note the /pwa), because if you open the TLD, it automatically redirects to our login provider, which is an external OAuth2 provider (and thus doesn't have a service worker and manifest).
Therefore we specifically made /pwa work without authentication.

Can anyone please help with that?

Thanks in advance :)

Best,
David
