AUTH311: Rest route missing

What this means

WCPOS can't reach its connection point on your store.

Ask your site admin to check the WCPOS plugin is active (WP Admin → Plugins) and that no security plugin blocks the REST API.

Your data

No order or product data is affected. Tell your site admin.

Troubleshoot

At the till — for the cashier: tell your site admin. Nothing on this device is affected.

On the store — for the site administrator:

1. Confirm WCPOS is active: WP Admin → Plugins.
2. If neither REST form works, check whether a security plugin, proxy or CDN is stripping WCPOS request headers or blocking REST requests — firewall rules and disable-REST-API hardening options are the usual culprits.
3. On some hosts, re-saving permalinks (Settings → Permalinks → Save) restores missing REST routes.
