Same for me.
A fresh installation, system diagnostic error about invalid certificate and the solution of tpfann (step 1, 2 and 3) worked for me.

Same here on a fresh 5.0.4.
Step 1, 2 and 3 and everything ist OK

#107

Same here before going from 5.0-4 to 5.0-6

  1. wget -O /etc/univention/letsencrypt/lets-encrypt-r3.pem https://letsencrypt.org/certs/lets-encrypt-r3.pem

  2. ln -s /etc/univention/letsencrypt/lets-encrypt-r3.pem /usr/local/share/ca-certificates/lets-encrypt-r3.crt

  3. update-ca-certificates

And the problem was solved.
