  │   HTTP     http://myapp.localshare.io
  │   Local    localhost:3000

Troubleshooting

DNS not propagating

DNS changes can take up to 48 hours to propagate. Check with:

dig myapp.example.com CNAME

Certificate errors

Make sure your CNAME points to tunnel.stunl.io and DNS has propagated. stunl automatically provisions TLS certificates for verified domains.

"Domain not authorized" error

Verify domain ownership in the portal. Make sure the TXT verification record is correctly configured.
