CA-0078: TLS communication warning
Problem
The TLS (Transport Layer Security) handshake between
the DMS and the instrument failed.
The instrument still transmits results and receives
updated data from the DMS.
Possible reasons:
• Configuration issue (e.g., the configured certificate of
the DMS (stored in the DMS TLS certificate) has
expired.
• Cybersecurity issue (e.g., man-in-the-middle attack).
Solution
Check the certificate stored in the DMS TLS certificate.
If the configured certificate has expired, update the
certificate and set the DMS TLS certificate check
configuration item to Strict again.
Check the connection between the instrument and the
DMS using the network status test.
Check your network infrastructure for breaches.
Connect the instrument to a separate network and set
the DMS TLS certificate check configuration item to
> Warning in order to allow a connection to the DMS.
