[Windows 11] wails dev fails to bind to port 34115

[doteich]

Description

I am not able to open the dev server on port 34115 (build works just fine). Using Curl/Test Net Connection tells me, that nothing on that port is running, so i am only able to reach the default vue.js dev server for the frontend on localhost:5173. I also tried to set a different URL via wails.json or the command line flag. From the console, everything looks fine and I dont see any errors.

 INFO  Wails is now using the new Go WebView2Loader. If you encounter any issues with it, please report them to https://github.com/wailsapp/wails/issues/2004. You could also use the old legacy loader with `-tags native_webview2loader`, but keep in mind this will be deprecated in the near future.

Hi,

Are you saying that you can access the webpage via http://localhost:34115 but running curl requests for the same is unsuccessful?

[doteich]

Hi, its actually both. I can't access the webpage and curl returns unsuccessful. To check if it is some issue with the port, I also ran a quick http-server http.ListenAndServe("localhost:34115",nil), which worked just fine.

Hey,

Unfortunately, that repro is working fine for me with no issues, so my current guess is some sort of issue with your environment or setup. This is a windows installation it looks like, has this ever worked before? Does this do anything for you? wails dev -devserver localhost:34117 https://wails.io/docs/reference/cli/#dev

I'm experiencing exactly the same behavior but with Mac M2. Also tested wails dev -devserver localhost:34117 but no luck. Below is the details:

Just FYI, not sure if that was the root cause, but using these deps via rtx seems to have fixed my issue:

• go 1.19
• node 18.19.0

Hi all, rookie mistake from my side. Issue was, that I had the Go installed for Arch "386" while it should have been "AMD64". Recently updated to a newer go version and it works now.
