403 when running Workbench Instance

I was running User-managed notebooks before with the same settings having no issue.

Now I’m running new instance and want to use Jupyter Notebook UI.

I’m running instance from service account.
For fast troubleshooting I have all these roles:

  • Service Account Token Creator

  • Service Account User

  • Vertex AI Administrator

Service account has everything like:

  • Vertex AI Service Agent

  • Compute Instance Admin (v1)

  • AI Platform Notebooks Service Agent

I couldn’t troubleshoot it myself. I can connect to the instance via my ssh and run jupyter this way, but I can’t normally impersonate the service account when doing ssh. Moreover I would need this Vertex UI running for other team members
