Troubleshooting

  • Studio loads but no data: check backend gRPC is running on the expected port (--backend-port) and that there is no firewall blocking the connection.

  • Port conflict: weightslab start auto-selects the next free port and logs it; or pass --port PORT to pick a specific one.

  • No plot updates: check plot auto-refresh setting and backend logger data.

  • TLS errors with –certs: run weightslab se first to generate certs, then export WEIGHTSLAB_CERTS_DIR.

  • Connection refused on remote backend: use weightslab tunnel to forward the remote port locally.
