A StatusCode of
10077 is an SSL issue related to resolving an SSL CA certification. Usually, the issue is local to the player's device or network. The Vivox SDK uses SSL and TLS to establish HTTPS and TCP connections. When the SSL/TLS certification validation cannot be completed for some reason, a 10077 is often returned as a StatusCode.
Note: For mobile devices, one root cause is the device system time being significantly wrong, often by a month or more. However, for other platforms, some game anti-cheating software interfered with SSL processing on some older Windows platforms, often Windows 8.
