ok, note that I am able to connect to the Ignition OPC UA Server, now I am not able to connect to the remote opc-ua server.
This was working before with 8.0.2RC1. Now at 8.0.2 I am getting similar errors as before.
Ok, after deleting the cert…pfx files and restarting… I am getting different connection refused errors.

If I disconnect the ignition server from network. I am able to communicate with the opcua server using FreeOpcUa client. It does not time out in this case. Once I connect ignition server, both clients will get the same connection refused.
ConnectionRefusedError: [WinError 10061] No connection could be made because the target machine actively refused it

I was able to browse the directory with the Ignition designer and read and write values using the ignition quick client, before upgrading to 8.0.2
I don’t know if this issue is the same as original. I thought it was because the first exception included “PKCS12KeyStore”… but now this might be another issue. Maybe independant or closer related to my original Uint32 post. Please moderate however you feel is best.
This shows connected. Then ignition sends several packets to the opc server. what is being sent and why? This happens before even adding to a project as a tag. We are able to use this with the older versions and a polled/on demand scan class group. In 8.0.2 it is different.
The ReadRequest that the server is closing the connection in response to contains 167 items. I’m guessing that you have 167 tags defined for this server and are using an OPC Read Mode tag group as discussed previously.
It’s possible this is too many tags to read at one time from this server. The read for the operation limits is failing with Bad_NodeIdUnknown, so the client is just falling back to default values. A correctly implemented server would be responding with Bad_TooManyOperations in this case, rather than closing the connection, but who knows.
You can try changing the “Max Per Operation” setting on the OPC UA connection to 50 or 100 and see if it helps. You really need to get the vendor of this server involved, though, because it seems to be kind of a poor implementation.
I am facing similar issue with one of the OPC connection, error -
