Curl NSS error -12190 - Erro no handshake de TLS

Question

Estou com erro abaixo ao tentar fazer o download de um pacote de uma URL por meio de putty:

O proxy respondeu OK ao pedido CONNECT

Initializing NSS with certpath: sql:/etc/pki/nssdb

CAfile: /etc/pki/tls/certs/ca-bundle.crt

CApath: none

NSS error -12190

Error in TLS handshake, trying SSLv3...

Mas para alguns URLs, funciona perfeitamente como abaixo:

Alguém poderia me ajudar a corrigir isso?
