fullstack web app dx serve "o" hotkey causes backend to crash

[Zer0dot]

Problem

When I run a fullstack webapp, even the "hello-world" example, and press "o" to open the webapp in my browser (Vivaldi), it errors with:

called `Result::unwrap()` on an `Err` value: Os { code: 98, kind: AddrInUse, message: "Address already in use" 

Tracing back the error to the invocation of dioxus::launch(App).

Then, I get spammed with

Application [server] exited with error: exit status: 101 

first as a [dev] notice, then after CTRL-C-ing, as an ERROR notice.

Note that copying the url, or ctrl-clicking the url shown in dx serve works fine.

Steps To Reproduce

Steps to reproduce the behavior:

• dx serve a fullstack app
• press "o"

Expected behavior

Opens the webapp in the browser of choice.

Environment:

• Dioxus version: dioxus 0.6.1 (c2952a7)
• Rust version: 1.85.0-nightly (7f75bfa1a 2024-12-30)
• OS info: Debian 12 Bookworm on a dual boot setup.
• App platform: web

I'm faaaaaaaaairly certain this may have to do with my environment.

Same for me.

Environment:

• Dioxus version: dioxus 0.6.1
• Rust version: 1.85.0-nightly (7f75bfa1a 2024-12-30)
• OS info: Windows 11 on a dual boot setup.
• App platform: web

Btw. Thanks @Zer0dot I was struggling with this issue for hours and did not think about simply copying the URL instead of pressing 'o'

Can also confirm this error and this work around.

• Dioxus version 0.6.0
• Rust Version 1.83.0
• OS info Nixos
• App platform Web + Fullstack
