This has just appeared my desk. I suggest you we the *.repec.org wildcard
  certs instead. They are here

root@siche ~ # ls /etc/letsencrypt/opt/live/repec.org/
cert.pem       chain.pem      fullchain.pem  privkey.pem    README         

  Their home is on iripa, but they are mirrored all other servers.
