pquiring opened a new issue, #1958:
URL: https://github.com/apache/plc4x/issues/1958
### What happened?
PlcConnection plcConn =
PlcDriverManager.getDefault().getConnectionManager().getConnection("s7://10.48.61.20);
Method never returns. Using WireShark I can see TCP connection was
established but no data is transmitted.
Not sure why some output is not in english.
OS : Windows Server 2022
Java : 17
Netty : 4.1.63 (last one that included -all build -- alternative is to
include 40+ deps - foobar!)
Here is log output:
