What issue can arise with connectivity between Dynatrace and your cluster due to a TLS handshake error?

A TLS handshake error occurs during the process of establishing a secure connection between two parties, such as Dynatrace and your cluster. One common issue that can lead to such an error is when the certificate involved in the handshake is either invalid or expired. This could happen if the certificate does not match the hostname, if it has been issued by an untrusted authority, or if it has reached its expiration date. When the server presents a certificate that falls into these categories, the client may refuse to complete the handshake, resulting in a failure to establish a secure connection. Thus, an invalid or expired certificate can directly disrupt the communication needed for Dynatrace to monitor and manage your environment effectively.
