An Xtream Codes error blocks channel access. Here is what the most common codes mean and how to fix them.
401 Unauthorized
Invalid credentials. Check username, password and server URL. Watch the case: Xtream Codes is case-sensitive.
403 Forbidden
IP blocked or expired subscription. Temporarily disable your VPN or contact your provider to check status.
404 Not Found
Wrong server URL. Check the port (often :80, :8080 or :8880) and that the address starts with http:// or https://.
503 Service Unavailable
Server under maintenance or overloaded. Wait 15 minutes and retry. If it persists, contact support.
MAX_CONNECTIONS / Connection limit reached
You are using the plan on too many devices at once. Sign out of one device or add an extra line.
Permanent buffering
Not strictly an Xtream code, but often caused by insufficient bandwidth or a slow DNS. Test your connection and switch DNS (1.1.1.1 or 8.8.8.8).
