I just updated to 9c04a82c3128 and "isabelle components" tells me that there are
many missing components, but dowloading fails for the first one:

Getting "https://isabelle.sketis.net/components/e-2.6-1.tar.gz"
Failed to download "https://isabelle.sketis.net/components/e-2.6-1.tar.gz"

Since compiling Isabelle (Scala sources) fails, probably because of some missing
component, I am stuck.

Any suggestions anybody?

Update: after I downloaded the 10 or so missing components via a browser and
moved them to .isabelle/contrib, everything seems to be back to normal.

Can you say what your version of macOS is?

I've recently seen problems with HTTPS certificates for old versions, but did
not manage to isolate the problem yet.

Big Sur was fine, as well as various Linux and Windows installations.

OK, this is one of the versions that don't work.

I will take another look at the web server for
https://isabelle.sketis.net/components to see if something can be changed with
the certificates. (This will coincide with a general move from Apache + Let's
Encrypt towards Caddy and its automatic certificate management.)

I was able to update without problems. I’m on Big Sur.

Yes, this only affects older macOS versions, and there only the "curl" tool.

Here are some more explanations:

https://letsencrypt.org/docs/certificate-compatibility

After looking through this briefly, I've now produced the following
workaround, to degrade HTTPS in curl on macOS 10.x (everything before Big Sur):
