I have a problem with some devices in the OPCUA device connections that remain in a Not Connected state although there is a connection that i have checked via multiple ways. I have tried to connect from the Ignition server to the device via SSH connection which is working properly. Also the device is pinging and there is no firewall rule that may interupt the connection. These devices are Opto22 SNAP-PAC-R2 PLCs. I have a big project with almost 200 of them and this occured only in 2 that refuse to connect in the UI. Any idea will be more than helpful.
Thank you all.
