Yes, thanks for pointing that out. I'm using certbot, and it seems to
run happily without attention once set up.
I had to sort this a couple of years ago - running a web site at home
for a small choir, I found some members' phones were so security minded,
https was mandatory. Chrome on my android tablet is equally annoying, as
it won't access what it thinks are unreasonable web ports; which I use
for marginal extra security. Some kit is too smart to be useful.
