ctrlX core not accessible on network

Hello, and thanks for the swift reply. My issue with it is that is that, despite having different IPs within the same range, and having a direct connection between the PC and the core, and nothing else, ctrlX Works still can't detect it. The PC's IP has been adjusted accordingly (not DHCP). If I ping the core's IP, I can see that the mac-address is the same as the core's, so I'm able to ping it, and not just some random device on the network. Lastly, I've checked that ctrlX Works is not being blocked by the firewall. Curiously enough, I used the exact same setup at my Bosch-Rexroth training, and everything worked fine, so I'm not entirely sure what could have been changed since then. Thanks, once again.

Edit: I managed to get ctrlX Works to see the core, via a virtual machine, but I still had no brower access to it (it kept saying "the requested URL was not found on this server"). I had to start PLC engineering, compile and download an empty project onto the core, stop the "PLC" and, only then, was I able to access the web environment. Not sure if this was a single or multiple issues happening at the same time, but it's now working, at least for the time being. Thanks for your help.
