make fetchindex in /usr/ports failing with Authentication error

[Bob Willcox]

I just updated my /usr/ports on my 13.0-current system and after that completed I tried to
run 'make fetchindex' and got a continuous stream of these errors written to the display:

fetch: https://www.FreeBSD.org/ports/INDEX-13.bz2: Authentication error
Certificate verification failed for /C=US/O=Let's Encrypt/CN=Let's Encrypt Authority X3
34370576384:error:1416F086:SSL routines:tls_process_server_certificate:certificate verify failed:/usr/src/crypto/openssl/ssl/statem/statem_clnt.c:1915:

Anyone have any idea what I have wrong or am missing? This was previously working on this
system (and make fetchindex works on my 12.1 systems ok).

Thanks,
Bob
