I'm afraid this might be a windows issue, but I hope you can help! I've cloned and built both the master 3.9 branches of OpenRefine and have the same problem. I'm building in an Ubuntu window in Windows 11. The builds go just fine and when I run ".\refine", the server starts up and a Chrome browser tab opens, pointing to [http://127.0.0.1:3333](http://127.0.0.1:3333) with the message "This site can’t be reached". But, when I open another Ubuntu window and use curl to get to the same URL, I get a lovely page of OpenRefine HTML. I've tried this with the Edge and Firefox browsers and get the same result. Any thoughts on what is going wrong? Ralph ---

If you mean by "Ubuntu window" that your running an Ubuntu distribution through WSL, then you might need to pass further options for networking. But most of the time WSL defaults just fine with NAT (network address translation) and thus `localhost` is available. So try instead [http://localhost:3333](http://localhost:3333) Reference: [Accessing network applications with WSL | Microsoft Learn](https://learn.microsoft.com/en-us/windows/wsl/networking) ---

interesting. Sure enough, the problem was access to the service running in WSL. I started up the service from the Windows command prompt and Chrome had no problems getting to it. It doesn't display a very interesting screen and the developer tools reports some missing files. I'll keep fiddling, but thanks for the clue! ---

FYI, I just use the new mirroring mode, that you can read in that article as well, maybe it "just works" for you?
