Hello blade;

In my case, I'm running my own mail server. I had to generate a new
cert on that. But before I could get my iPhone (running iOS 15) to
'see' the cert I had to restart that as well. As soon as the iPhone was restarted it had no issues using the new cert.
I run my own mail server and a few for clients as well. The server itself has had no issues as when LE finally installed a valid cert for themselves it was fine and I didn't have to regenerate a new cert. The apple devices however that I'm stuck dealing with are iOS 14 or lower and they don't seem to easily handle the updated LE cert. The local mail server cert is fine, it's LE that had the issues. It's not just Apple either, M$, google, Cisco, and lots more have suffered this. From what I've read, it's hit or miss with iOS 15.
