Problem
An error message similar to the one below is shown (The secure sequence number xxx expected by the device is implausible and cannot be used):
Cause
This issue is significant and indicates that something unusual is occurring with the device. It could signal a serious malfunction within the device's hardware, potentially compromising its normal operations. Alternatively, this anomaly might be the result of a targeted attack aimed at breaking the device's security protocols. Another possible cause is a change in the PC's system clock, which can disrupt the synchronization required for secure sequence numbers, leading the device to reject them as implausible. Each of these scenarios warrants immediate investigation to protect the integrity and security of the system.
Solution
To address the issue of implausible secure sequence numbers, it is essential to perform a factory reset on all affected devices. This action will restore the devices to their original factory settings, eliminating any potential causes of the problem, whether due to hardware malfunctions, security breaches, or system clock changes.
To perform the factory reset, please check the product specifications and user manual specific to each device. These documents provide essential instructions and guidelines on how to safely and effectively carry out the reset procedure.
