This question has been deleted because the site is having unexpected behavior.
your http is online and answers with a redirect http -> https.
But your https doesn't answer.
Is there a blocking firewall or a not configured router port 443 extern -> port 443 intern?
Checking your domain - chub.gdslab.org - Make your website better - DNS, redirects, mixed content, certificates - you see: http has the redirect, https a simple timeout.
And there is a new certificate.
Works https from that machine?
@JuergenAuer This web is running on an instance on the Oracle Cloud. I checked earlier and the Ingress Rules allowed traffic for port: 80, but not for port: 443. I just included it and it is working as expected.
Thank you very much for your prompt assistance!!
