===== RESPONSE ERROR (ServiceCode=AuthenticationFailed) =====

Description=403 Forbidden, Details: (none)

Cause

Your edge node's system clock may not be properly synchronized with the Network Time Protocol (NTP) server, in which case, when the date field in the request header differs from the server’s date by more than fifteen minutes, the server may consider the request as a replay attack. To protect against these attacks, the server will reject suspicious requests, causing the authentication process to fail.

Solution

Ensure your edge node is synchronized with the NTP server.
