You are no trying to connect to a KNIME Server but to Twitter (the error message comes from the Twitter Search node). This topic is about connecting to a KNIME Server.
Since I assume that Twitter uses a certificate that is accepted by almost anyone my guess is that there is a proxy or firewall between the workflow and Twitter which tries to sniff the encrypted traffic and presents a forged Twitter certificate.
