Letsencrypt verification failed

[Mornsgrans]

This is the thrid thread about issues with Letsenrcyt.

See my opions here:

Let's Encrypt fails to renew / verify certificate in UCS 4.4-2 errata-291: traceback error in logfile

If I see it right, Letsencrypt has issued new root and intermediate certificates, but the Letsencrypt app of Univention still is on an old release.
