The error wasn't a restriction. It was a mercy.

The "Operation not allowed" error in K-TAG typically occurs during the reading or writing process and indicates that the software has blocked the specific action you are attempting . ktag operation not allowed

: Ensure your PC is online; K-Suite needs to verify protocols with the Alientech server. Update K-Suite
