acme-challengetoken mentioned in the message does not exist in the common challenge directory:

With debug mode enabled, it is possible to see that the certificate renewal was skipped in
/var/log/plesk/panel.log:
CONFIG_TEXT: DEBUG [extension/sslit] Skip certificate renewal for domain 'example.com': the certificate will expire in more than 30 days at YYYY-MM-DD
- There was a previous issue with certificate renewal that has been recently resolved;
Cause
The certificate has been recently renewed, but notifications for previous failed renewal attempts can come with a delay. This is an SSL It! extension bug #EXTSSLIT-1922.
Resolution
Notifications for failed renewals can be delayed for 24 hours. No action is required.
If notifications keep coming after a while, check the email headers to make sure that they are not coming from an old server.
