Troubleshooting

Start with /api/health

Open /api/health and confirm ok, database status, hasSplitDbEnv / hasDatabaseUrl, and Google/Microsoft OAuth flags. Fix env via Hostinger hPanel restart when possible.

Common failures

• Configuration / sign-in error — DB unreachable or auth tables missing. Push schema (npm run db:hostinger:push) after enabling Remote MySQL if build-time push hit EACCES.
• Insufficient scopes — Re-authorize Google from Connect so Ads/GTM scopes are granted.
• Ads sync fails — Verify developer token and Ads customer IDs on the site.
• Bing missing_config — Set Microsoft client ID/secret and matching redirect URI.
• 503 after deploy — Confirm hPanel Framework is Other, entry app.js, output ./.

Local vs production DB

Local USE_SQLITE_DEV=true ignores Hostinger MySQL. Production must leave that unset and use DB_HOST=localhost on the Node host.
