This message means the server is rejecting access based on missing or invalid tokens. It often occurs when stream protection methods (like anti-leech or URL tokens) are active. Go to Manage Users > Security Settings and verify if IP locking, country restrictions, or MAC binding is turned on. Also, ensure the player being used sends the correct headers. If using secure links (like signed URLs), tokens may have expired. Check the logs under /home/xtreamcodes/iptv_panel/logs/streaming.log to trace the actual cause.
