Wsl Ubuntu error: Agent server started but is not accepting connections

[Sergsun]

Description

Hello,

I am trying to run agentcore dev in a wsl Ubuntu on Windows and 8/10 times I get the following error:

The only way to avoid this and actually run the dev UI properly is to keep stopping and starting agentcore dev again until it starts working.

Steps to Reproduce

1. run wsl -d Ubuntu
2. run agentcore dev
3. Wait until you get the error
4. Keep relauching the dev server until the server starts normally

Expected Behavior

I expect the dev server to start on the first try

Actual Behavior

The server only starts after relauching it and getting the error a number of times, and the number is always different, which suggest it's a random one.

CLI Version

0.26.0

Operating System

Windows

Additional Context

The cli is run is Ubuntu wsl. The log files are not populated when the error occurs.
