DevContainer hangs with resolveAuthority waiting - extension 1.0.26

[juarezr]

Issue

Cursor's devcontainer extension gets stuck with [resolveAuthority(dev-container,1)] waiting... when opening devcontainers. Same configuration works perfectly in VS Code.

Environment

• Cursor: 2.0.77
• Extension: anysphere.remote-containers-1.0.26
• OS: Linux (Ubuntu 25.04)
• Docker: 29.0.1
• VS Code: Works correctly with same setup

Steps to Reproduce

1. Open workspace in Cursor
2. Press Ctrl+Shift+P > "Dev Containers: Reopen in Container"
3. Process hangs with resolveAuthority waiting message

Expected

Devcontainer connects successfully (as it does in VS Code)

Actual

• Devcontainer CLI process hangs indefinitely
• Process stuck waiting on pipes (FIFOs)
• Container runs fine but VS Code server never installs
• Extension host logs show thousands of "waiting..." messages

Evidence

• Container is running and accessible
• Same devcontainer works in VS Code
• Process stuck on pipes: lsof shows FIFO pipes open but no data
• Started after Cursor version update
