A timeout during a TLS handshake can result in the connection failing to terminate. This can result in a Niagara thread hanging and requires a manual restart of Niagara (Versions 4.6.96.28, 4.7.109.20, 4.7.110.32, 4.8.0.110) and Niagara Enterprise Security (Versions 2.4.31, 2.4.45, 4.8.0.35) to correct.
