I am trying to connect an machine to the Ignition Server using an OPC-UA card, but I am encountering the following error on the server side:
sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
I have tested the same scenario in a local environment by connecting the machine directly to a laptop, and the communication works successfully. That setup is not restricted by any network security policies.
However, when I attempt to connect the machine to the Ignition Server within the server/network environment, the connection fails with the above error.
Thank you.
