1. BMU did not start normally.
2. BMU address input error.
3. Solve the SSLv3 vulnerability, resulting in IE8 browsers unable to access BMU.
In order to fix the SSLv3 vulnerability, the server of eSpace UC V200R003C00SPC100 restricts the access policy of clients. Because the IE browser of XP operating system supports IE8 at the highest level and does not support TLS1.1 and TLS1.2 protocol, the client computer can not access BMU and personal Portal. If the computer that supports XP system can access BMU, it is necessary to return the configuration of BMU server, but it is backward. Configuration operations can lead to the re-exposure of the SSLv3 vulnerability (win7 and later versions of the operating system only need to change the IE browser configuration). This problem will occur in eSpace UC V200R003C00SPC100 and later versions, eSpace UC V200R001C03SPC210 and later versions, and eSpace UC V200R001C50SPC203 and later versions.
4. Pay attention to password validity.
