Symptom

After signing in successfully, opening a workspace returns a red banner reading Access denied (AUTH-403). Other workspaces open normally.

Cause

AUTH-403 means your account is authenticated but is not a member of the workspace you're trying to open, or your membership was removed. It is a permissions issue, not a password issue.

Resolution

  1. Confirm you're using the correct account. Open My account and check the email shown matches the one invited to the workspace.
  2. Check whether you have a pending invitation in your email. If so, accept it and retry.
  3. Ask a workspace admin to confirm your membership under Members. If you're missing, request to be re-added.
  4. If you were recently added, sign out and back in to refresh your access token.
Still blocked?Access changes can take up to five minutes to propagate. Wait, then retry once before escalating.

When to escalate

If a workspace admin confirms you are a member but AUTH-403 persists after re-authenticating, contact support with your account email, the workspace name, and the exact time of the error so the team can trace the access log.
