Difficulties renewing a certificate in Plesk, using Let's Encript extension

Greetings,

My domain is: iamvexillum.com

I was trying to renew my Let’s Encrypt certificate trought Plesk, using the Let’s Encrypt Extension and the following error occured:

Could not renew Let’s Encrypt certificates for Administrator (login admin). Please log in to Plesk and renew the certificates listed below manually.
Renewal of the following Let’s Encrypt certificates has failed:

The following Let’s Encrypt certificates have been renewed without some of their Subject Alternative Names:

Legend:
[+] This domain is secure. The domain’s SSL/TLS certificate from Let’s Encrypt has been issued/renewed.
This domain is not secure. Either the domain’s SSL/TLS certificate from Let’s Encrypt could not be issued/renewed or the domain name was excluded from the certificate. Renew the certificate manually or request a new one to secure this domain.

Could you help me with this situation?

Thanks in advance.
