Unlike "Feature Not Found" errors (which imply a connection was made but the specific license is missing), Error 7502 usually implies that the license request could not physically reach the server daemon, or the server's response was blocked.

This is the single most important step and the most common cause. You should check this before moving on to more complex steps.
