V8.1.45 Connection issues to Rockwell PLCs

Ignition
1

Having an issue with an Ignition upgrade. Migrating from V7.9 to V8.1 on a new server. The new server is on 192.168.3.XXX subnet and PLCs are on 192.168.10.XXX subnet. I can ping PLCs from Ignition Gateway, using Test-Connection -port 44818 from Windows PowerShell confirms port is open.

Original gateway was on the 192.168.10.XXX subnet and I just backed up and restored on the new Gateway . The PLC drivers will not connect to any of the CompactLogix PLCs , all V24 or higher firmware.

Am I missing something in new Gateway ?

Run wireshark on your gateway, filtering for one of the broken target IP addresses. Share it here.

(I'll bet the port really isn't open.)

Are you sure you have a default gateway/route set in both the PLC and the Ignition gateway pointing to the router that's able to route between the 2 networks? Many times I've seen the gateway get missed on the PLC side causing issues like this.

Need to wait on the customer's IT guy. No permissions to install Wireshark

Thanks.
need to wait for customer's IT guy. BUT, i can ping the PLCs on the 192.168.10.XXX subnet and use Web Browser to connect to PLCs , both from the Ignition Gateway on the 192.168.3.XXX subnet

Yeah, I'd wait on the IT guy (any chance his name is Larry or Moe? LOL) and see if they're blocking anything in relation to port 44818.

Edit: And maybe share your config on here to see how you've configured those drivers. (You are using the new Logix drivers right and not the older ones?)

Set the loggers under "drivers.LogixDriver" to DEBUG or TRACE and then edit/save one of the devices. Post the logs after something useful looks like it has appeared.

Note sure if any useful info in this.
I uninstalled Ignition, reinstalled and did not import project. Created only one device connection to 192.168.10.40, same results, not connecting

Issue has to be 'something' blocking port 44818 ( perhaps at managed switch ) as I can ping , but cannot connect to PLC via web browser ( contradicting what I stated earlier ) I can connect to PLC via my VPN connection with web browser.

Yeah, just wanted to confirm it's some kind of network problem and not an unexpected driver bug or something.

It does looks like a network problem, not something you can configure your way out of in Ignition.

This is what I get, also ran PING to PLC

That's exactly what I'd expect to see alongside the error message above.

Ignition tries to open a TCP connection (SYN) -- no response.

as suspected, ports were being block at the host machine, not the VMs
