Slack connector shows connected but Codex returns invalid_auth_token

Hi team,

I’m trying to use the Slack connector in Codex, and the connector appears connected in Settings > Connectors. I can see my Slack workspaces listed there as connected.

However, when Codex tries to read Slack, the tool calls fail with:

invalid_auth_token

What I already tried:

• connected Slack recently
• refreshed the page
• retried in the same chat
• verified the workspace appears under Settings > Connectors

Observed behavior:

• UI shows Slack as connected
• Codex cannot read Slack data and consistently returns invalid_auth_token

Expected behavior:

• once Slack shows as connected, Codex should be able to read Slack context successfully

This looks like a stale or mismatched backend token/session rather than a missing setup step in the UI.

If helpful, I can also provide the connected workspace names shown in Connectors and the approximate time I reconnected Slack.
