I add these config in build/darwin/Info.plist, and retry rm -rf build/bin && wails dev, it works now haha

Awesome! Thanks for letting us know. This was a great suggestion. Here’s a virtual beer 🍻 👍

Tried it out, and works perfectly! Thanks for fixing this, sorry about the delay in testing it.

I can confirm that the minimal fix above works with Vue3 and Vite. Thanks for the fix!

@stffabi your settings works~~ 👍 Thank you very much for your patient guidance 😃

@cxt90730 awesome that it works now for you 👍

We would like to document this in a troubleshooting guide #1508 . It would be great to find the minimal settings needed to get it working, especially Apple has a “AllowLocalNetworking” flag. Would it be possible for you to give the following settings in your Info.plist a try, that would be awesome?

<key>NSAppTransportSecurity</key>
<dict>
    <key>NSAllowsLocalNetworking</key>
    <true/>
</dict>
