I received the following email from Let's Encrypt today:
I'm sure this will not affect my running the forum on the NAS, but thought others on here might be interested in what they are saying?
Hello from the staff at Let's Encrypt.
On September 30, there will be a change in how older browsers and
devices trust Let's Encrypt certificates, resulting in a minor decrease
in compatibility. If you run a typical website, you won't notice a
difference. Devices and browsers running up-to-date software will
continue working fine, and we've taken steps to make sure the vast
majority of older devices will too. If you run a large website, or need
to support less common software (particularly non-browser software),
you'll want to read about the details at:
DST Root CA X3 Expiration (September 2021) - Let's Encrypt
In either case, no action is required from you. We're letting you know
so you can provide answers to any questions your site visitors may have.
Here is a sample hostname from one of your current Let's Encrypt
certificates: forum.t3kk.com
Since 2015 we've served the world with 1.6 billion free certificates,
each one providing security and privacy to people on the Web. It's work
that's 100% funded by charitable donations since we are a nonprofit. If
