Resolved SSL It! - Failed to apply synchronization: GET request to Mozilla security service failed: Host must be a string

[Jelle_Timmer]

I recently updated one of our servers from Onyx to Obsidian. From that moment, it seems like SSL 1.0, 2.0, 3.0 and TLS 1.0, 1.1 are again accepted.
Trying to set these using 'SSL It! > TLS versions and ciphers by Mozilla' results in the following error:

Failed to apply synchronization: GET request to Mozilla security service failed: Host must be a string

In the panel.ini log, the following lines appear:

[16-Apr-2020 07:59:07 Europe/Berlin] PHP Warning: Use of undefined constant INTL_IDNA_VARIANT_UTS46 - assumed 'INTL_IDNA_VARIANT_UTS46' (this will throw an Error in a future version of PHP); File: /usr/local/psa/admin/plib/modules/sslit/vendor/guzzlehttp/guzzle/src/Client.php, Line: 221

These error-messages look similar to the ones in the following (confirmed) issue: Issue - Lets Engrypt - Could not obtain directory: Host must be a string

It looks like they're related, but I am not entirely sure.

Can somebody confirm this issue (or explain how to fix, if it's not a confirmed issue)?

OS: CentOS 6.10 (Final)
Plesk: Obsidian 18.0.26
- SSL-It! 1.3.0-677
- Let's Encrypt 2.9.0-611
