I have not seen this either.. What are the network adapters you have on your windows system? Also, you could debug this a bit more by adding `-Djavax.net.debug=all` to a new file called `designerlauncher.l4j.ini` next to the `designerlauncher.exe` file. ---

Hi Team I've tried everything to get this designer software working, including uninstalling and reinstalling both the designer and Ignition, restarting my computer, and even removing the latest Windows updates. Is there any other workaround I can try? Thanks ---

Hi Team Found a solution I downloaded and installed Designer Launcher version 1.1.24. When I tried to open the Designer, a popup appeared indicating that the Ignition version is 1.1.37 and asked if I’d like to update. I chose to ignore the prompt, and it's working fine now. (For reference, my previously working version was 1.1.37.) Thank you all for support.
