Doesn’t matter what version of Ignition (tried various 7.2.11 through 7.5.11 installs) or Java (6uX’s and 7uX’s) but get a segmentation violation. While it still seems to work on the surface, I can’t seem to make an external connection to the OPC Server. Any ideas?

Is the same segmentation violation error in any Gateway wrapper logs? I would think that there would be some sort of error in there when trying to connect to the OPC server. Also, do you use the OPC-COM module at all? ---

EDIT: Never mind. I found it. 😊 Just noticed from looking at the wrapper log that it bound itself to the wrong ethernet port for the endpoint. Maybe I didn’t leave myself enough vacation time… 😃 EDIT to my EDIT: Ok, I take it back a bit. It works, but I’m still confused about the segmentation error. it only comes up in the install log. Here’s a wrapper log from what’s currently working. There’s a bunch of IOException errors in it.
