Issue LetsEncrypt Certificate couldn't be renewed

[Oldiesmann]

I got an email today saying that the Let's Encrypt certificate for my main domain (the one used for the server hostname) couldn't be renewed...

] * 'Lets Encrypt certificate' [days to expire: 25]
   [-] server.iwannabea.ninja

   idn_to_ascii: empty domain name: U_ILLEGAL_ARGUMENT_ERROR

I'm going to go ahead and renew it manually for the time being, but is there something I can do to resolve this in the future?

I'm running Plesk Onyx 17.9.12 on Ubuntu Server 18.04.2 LTS if that makes a difference.

Today I get this mail too for plesk obsidian 18.0.28 with Let's Encrypt Version 2.11.0-639

Strange thing... two mails for same subdomain (hostname). First its renewed and

Date: Wed, 05 Aug 2020 09:16:03 +0200 = Let`s Encrypt certificates for XXX have been issued/renewed
Date: Wed, 05 Aug 2020 09:16:04 +0200 = Could not issue/renew Let`s Encrypt certificates for XXX

Here second mail:

Renewal of the following Let`s Encrypt certificates has failed:

* 'Lets Encrypt hostname.example.com' [days to expire: 29]
[-] hostname.example.com

idn_to_ascii: empty domain name: U_ILLEGAL_ARGUMENT_ERROR

This domain (hostname) have a valid certificate.
