Since today I get a “invalid certificate name” warning for blog.metabrainz.org.
The certificate itself points to “wordpress.com” (issued from “Let’s encrypt”).
Am I the only one receiving this warning?

This blog is hosted by WordPress, so even though Let’s Encrypt-based automation normally takes care of automated cert handling, there seems to be an issue. This documentation page likely applies.

Yeah, “smart” phones fall out of support really quick.
Your must be brand new (or more expensive).
