### What happened? Hello, I'm currently testing the PLC4X SDK to establish a connection to an OPC UA server implemented using Eclipse Milo, which uses a 4096-bit certificate. The server certificate is generated by Eclipse Milo, and the corresponding public key has been successfully extracted. The client certificate is generated as follows: (details to be added later) The connection already works without issues using other OPC UA clients (with support for 4096-bit certificates), so the setup appears to be correct in general. However, using the PLC4X SDK, I am encountering issues when trying to establish the connection. I suspect it may be related to the certificate length or trust configuration. I would appreciate any help or insights you could provide on this matter. Thank you very much in advance!
