# Troubleshooting

> What the common errors mean and what to do about them.

## The client never asks me to sign in, or loops on sign-in [#the-client-never-asks-me-to-sign-in-or-loops-on-sign-in]

Check the URL. It must be the exact value from the dashboard's MCP settings, ending in the workspace id. A bare `/v1/mcp` answers `404`. Some clients cache a failed registration; remove the connector and add it again.

## 401 Authentication required [#401-authentication-required]

The client sent no token, or one the server does not recognize. An API key or a CLI session in the token field causes this too; the connector takes OAuth only. Sign in again from the client.

## 403 This account has no active membership in the requested workspace [#403-this-account-has-no-active-membership-in-the-requested-workspace]

The account you signed in with is not a member of the workspace in the URL, or the membership was deactivated. Ask for an invite, or fix the URL.

## 403 No active workspace for this account [#403-no-active-workspace-for-this-account]

The account exists but belongs to no workspace at all. Create or join one in General Input first.

## 503 Authentication service temporarily unavailable [#503-authentication-service-temporarily-unavailable]

The server could not reach the service that resolves your token. Retry in a moment; nothing about the connector's configuration is wrong.

## A tool fails with "The workspace sandbox is unavailable right now" [#a-tool-fails-with-the-workspace-sandbox-is-unavailable-right-now]

The sandbox pool could not provision or adopt a pod. This arrives as a failed tool call rather than an HTTP error, so the assistant sees it and can retry. Nothing is lost, since `work/` is checkpointed after every call that changed it.

## The agent says a browser login is not available over this connector [#the-agent-says-a-browser-login-is-not-available-over-this-connector]

The browser sign-in handoff needs a live view a person watches, which the connector cannot open. The tool result says only that; it does not tell you where to go. Sign in to the site from the dashboard's browser page or with [`geni browser request-login`](/cli/browser/request-login), then ask the assistant again.

## The agent keeps asking me to confirm every step [#the-agent-keeps-asking-me-to-confirm-every-step]

Your host is gating write tools on their annotations. Set the connector's tool permissions to always allow; see the client page for where that setting lives.

## Files I asked for do not open [#files-i-asked-for-do-not-open]

Download links expire after seven days. Ask the agent to send the file again.

## Getting help [#getting-help]

Include the workspace id from the URL and the client you are using. Nothing in the URL or a connector name is secret.
