I recently got the status code when trying to connect to a server. Could you please explain a little bit more about this error ?

BadDecodingError - 0x80070000 - Decoding halted because of invalid data in the stream.

Hi,

This indicates that your client is sending invalid service requests to the server or that the server does not comply to the OPC UA specification.
You can use Wireshark to look at the messages. If Wireshark is not able to display the requests, this is most likely a client problem.
