Account error
This is no coincidence; it is the result of Meta’s upgraded risk control algorithms. This article will reveal the truth behind these errors and provide practical solutions.
The root cause is usually not an incorrect password, but Environmental Risk Control. When the system detects low IP reputation or too many accounts associated with a single device, it actively blocks login requests. We recommend using an anti-detect browser with static residential IPs. If you encounter a 429 error, wait for 15-30 minutes to avoid worsening the block with frequent refreshes.
