Network error while installing database tables
Install wizard shows installWizard.errors.migrateNetworkError when the install-tables request fails at the network layer.
Why this happens
Request dropped before migrate finished, app restart, or proxy timeout. Schema/DB errors use Could not install database tables instead.
Diagnose and fix
1. Confirm the app is up; refresh; click install tables again (safe once on a new DB).
2. Verify DB settings still saved.
3. See Could not install database tables if a migrate error body appears.
4. See First-run install wizard / Troubleshooting a failed install.
