The error code is named after the “Alberta” protocol—an internal Ubisoft identifier for a specific type of session mismatch. The hexadecimal suffix fff0bdc0 acts as a debug stamp pointing toward a connectivity handshake failure.

The Alberta error exploded in frequency during late 2023 and early 2024 after specific server-side patches.

When their matchmaking relay or UPlay overlay services go into degraded mode, alberta-fff0bdc0 is the first error to appear.

⚠️ Only if you have a good cloud save.
