Hi all,

I have two ignition gateway one running on Linux and another running on windows. For the ignition running on windows, it can easily connect to Omron PLC through OPC connections/servers.  
However, for the one deployed on Linux, I can’t get the acknowledge from Omron PLC. Is this the system problem? Any suggestions will be appreciated!

Some pictures for debug:

Hello,

Based on the information provided in Wireshark, there appears to be a network related issue that’s preventing OPC-UA protocol from working successfully. The moment Ignition sends it’s requests, the packets are being dropped along the way based on the `TCP Retransmission` being stated immediately after. Based on this, I do not believe it’s a problem related to Ignition.
