[CalendarServer-users] SSLAuthorityChain does not work on 8.0

I’m getting spurious ‚certificate not trusted‘ errors on client programs on OSX 10.11.6
Server cert is from letsencrypt and worked so far, but:
- - -
[caldav3:local/etc/caldavd] root# openssl s_client -no_ssl2 -no_ssl3 -showcerts -connect caldav.lrau.net:8443
depth=0 CN = caldav.lrau.net
verify error:num=20:unable to get local issuer certificate
verify return:1
depth=0 CN = caldav.lrau.net
verify error:num=27:certificate not trusted
verify return:1
depth=0 CN = caldav.lrau.net
verify error:num=21:unable to verify the first certificate
verify return:1
Certificate chain
 0 s:/CN=caldav.lrau.net
   i:/C=US/O=Let’s Encrypt/CN=Let's Encrypt Authority X3
. . .
Verify return code: 21 (unable to verify the first certificate)
- - -

If I put Let’s Encrypt Authority X3 cert
in pem format into config dir and point SSLAuthorityChain at it, I get:
- - -
root# openssl s_client -no_ssl2 -no_ssl3 -showcerts -connect caldav3.lrau.net:8443
34379258024:error:14077410:SSL routines:SSL23_GET_SERVER_HELLO:sslv3 alert handshake failure:/usr/src/secure/lib/libssl/../../../crypto/openssl/ssl/s23_clnt.c:757:
no peer certificate available
No client certificate CA names sent
SSL handshake has read 7 bytes and written 297 bytes
New, (NONE), Cipher is (NONE)
Secure Renegotiation IS NOT supported
Compression: NONE
Expansion: NONE
- - -
These certs work with all other servers.
So what am I doing wrong?
