[SOLVED] CertFP issue on Irssi (libera.chat)

Hi everyone,
I'm trying to access on libera.chat using CertFP via TLS connection on Irssi.
I generated my own self-signed certificate via OpenSSL, then when i tried to search for my client fingerprint (as described in this guide https://libera.chat/guides/certfp.html# … o-nickserv ) via WHOIS, I simply doesn't find it (even if I read that i'm on a "secure connection via TLS")
In the Libera.chat connection status i found an "Irssi: Certificate Fingerprint [bla::bla::bla..] (SHA256)" , I tried to "CERT ADD [fingerprint]" via NickServ, but when I disconnect and re-connect to Libera, I got this message:
"warning Could not find client certificate [path certificare.pem]"
and then
"Cannot authenticate via SASL (SASL authentication failed)
Irssi: Connection lost to irc.libera.chat"

Someone can help?
Thanks

Fingerprint found with the following command.

openssl x509 -in [NAME OF THE CERT].pem -noout -fingerprint -sha512 | awk -F= '{gsub(":",""); print tolower ($2)}'

Solved!
