## Common questions

### Why might the browser not open after running dsh web, and what port should I check?

It listens on 127.0.0.1:3080 by default, so confirm the process with ps aux | grep "bin.js web". If that port is occupied, start it with dsh web --port 8080.

### How can I allow git-hosted plugins when allowBuilds blocks them?

Allow them in pnpm-workspace.yaml.

### How can I inspect the current DSH configuration?

Use dsh --dump-config to inspect the configuration before fixing the symptom.
