Common Errors

This article explains the most common error messages you may encounter in PropellerDeck and what to do when you see them.

"Authentication Required" (401)

This error means your session has expired and PropellerDeck cannot verify your identity. It is not a permissions issue — you simply need to sign in again.

Fix: Log out if you have not already, then log back in. See Logging In for steps. If you are repeatedly seeing this error shortly after logging in, try clearing your browser cookies and cache.

"Permission Denied" (403)

This error means you are authenticated (logged in), but your account does not have permission to access the resource you are trying to reach. This can happen if you are trying to access a workspace, file, or setting that your role does not allow.

Fix: You do not have access to this resource. Contact your organisation admin to request the appropriate permissions. Do not try to work around this error — it is an access control boundary.

"Not Found" (404)

This error means the page or resource you are looking for does not exist at the URL you used. The item may have been deleted, moved, or the link may be incorrect.

Fix: Check that the URL is correct. If you followed a link from within PropellerDeck and it returned a 404, the underlying resource (file, workspace, session) may have been deleted. Navigate back to the relevant section of the app to locate what you need.

"Token Budget Exhausted"

Your daily AI token budget has been used up. AI responses are paused until your budget resets at midnight UTC.

Fix: Wait for the daily reset, or upgrade your plan to immediately receive a higher token limit. The Founder plan has no daily limit. See Token Budgets and Upgrading Your Plan for more information.

"Connection Error"

PropellerDeck cannot reach the server. This is most often a network issue on your end.

Fix: Check your internet connection and confirm other sites are loading. If your connection is fine, try refreshing the page. If the error persists across multiple page loads, PropellerDeck may be experiencing a service disruption — check for any status announcements.
