You must re-enable RC4 and/or SSLv3 support on java
1. Go to Java installation folder
2. Open {JRE_HOME}\lib\security\java.security -file in text editor
3. Delete or comment out the following line "jdk.tls.disabledAlgorithms=SSLv3, RC4"
Especially RC4 could be the cause of the failure (Note: these protocols are disabled because they're unsafe)
try again: It should be ok.
