Using spring config server with git causing security group issue - spring-cloud

Question

I am now trying to set up using spring config server / spring config client and eureka server to do service discovery together. when I was using local file system to save configuration, everything is fine, but as soon as I change to gitHub to save configuration, I can not start spring config client, and I got this error message:
com.netflix.discovery.DiscoveryClient : Can't get a response from http://user:{cipher}AQBdTe9vjgOqANyfi+Ke5HYmhFJnuvsGJ+8FOqLgdMdFInJkVRzy9XngylNp9KlX2lwPI13jT7ceDjBs9w4B6A15akQTHHP1q9rWwMcLtVCCKGFgvXSgQF+WWIItxBmIDGG4bSgDYZ6XQWl66T84PxjTBygErpmAjn+X2BWdtWtVmjXzpMQMaHGpiyLPoGIQYF4j9ZGpl16Jx79+j6et6LStksrT3WxQuanhZwIkqZ827+2mlUB3kd5ocW7R0vC3JMGVZlGNfqYQwJIhSJ19lrq4gxm/zbGroYonW3QSHTiRlhlvOdovEua/0dCl6+s0iEHYZCBllr7jikEWmS5Px7U2TG8/eQkjR8pUbSN6OE+OI2ZZUCNOT+mi75ZeeN1OtdQ=#localhost:8761/eureka/null
Can't contact any eureka nodes - possibly a security group issue?

This is what I have:
In cofig server application.yml:
spring:
application:
name: spirent-config-server
cloud:
config:
server:
git:
uri: https://github.com/spring-cloud-samples/config-repo
#searchPaths: foo,bar*
server:
port: 8888
in config client:
bootstrap.properties:
spring.application.name= foo
spring.profiles.active= development
spring.cloud.config.uri= http://localhost:8888
and application.yml
eureka:
instance:
hostname: ${host.instance.name:frank1}
nonSecurePort: ${host.instance.port:8080}
metadataMap:
instanceId: ${host.instance.instanceid:frank_123}
client:
serviceUrl:
defaultZone: http://localhost:8761/eureka/
server:
port: ${host.instance.port:8080}
Eureka Server:
application.yml
server:
port: 8761
eureka:
client:
registerWithEureka: false
fetchRegistry: false
server:
waitTimeInMsWhenSyncEmpty: 0
bootstrap.yml:
spring:
application:
name: eureka
cloud:
config:
uri: ${CONFIG_SERVER_URL:http://localhost:8888}
From the exception, it seemed it is because discoverClient is not working, anything special for the configuration?
But if I change from gitHub to local file storage for configuration, everything is fine.
Thanks for your suggestion in advance.
Based on the spring cloud document, I am doing like this:
In application.yml of config server:
spring:
application:
name: spirent-config-server
cloud:
config:
server:
git:
uri: https://github.com/spring-cloud-samples/config-repo
#searchPaths: foo,bar*
encrypt:
key: abc
server:
port: 8888
In application.yml of Eureka Server:
server:
port: 8761
eureka:
instance:
hostname: localhost
client:
registerWithEureka: false
fetchRegistry: false
serviceUrl:
defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/
server:
waitTimeInMsWhenSyncEmpty: 0
encrypt:
key: abc
And in application.yml of config client:
eureka:
instance:
hostname: ${host.instance.name:frank1}
nonSecurePort: ${host.instance.port:8080}
leaseRenewalIntervalInSeconds: 5 #default is 30, recommended to keep default
metadataMap:
#instanceId: ${host.instance.instanceid:frank_123}
instanceId: ${spring.application.name}:${spring.application.instance_id:${random.value}}
client:
serviceUrl:
defaultZone: http://localhost:8761/eureka/
server:
port: ${host.instance.port:8080}
encrypt:
key: abc
But, the problem is after I started Eureka an config server, it is fine, no exception, but after I started config client, I got this same exception:
Can't contact any eureka nodes - possibly a security group issue?

Can anyone tell me where is my error? This only happened in using GIT as config server data source, but in local file data source, no error happened.
Thanks
These are my steps to try to resolve the key issues, but failed again:
download the "Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files" from Oracle, and follow instructions for installation (essentially replace the 2 policy files in the JRE lib/security directory with the ones that you downloaded).
Now if I run spring encrypt mysecret --key foo, it is successful, this means the JCE is installed correctly;
Creating a Key Store for Testing: using this:
https://github.com/spring-cloud/spring-cloud-config/blob/master/docs/src/main/asciidoc/spring-cloud-config.adoc#creating-a-key-store-for-testing
after updating the application.yml in my config server, the application.yml is this:
spring:
application:
name: spirent-config-server
cloud:
config:
server:
git:
uri: https://github.com/spring-cloud-samples/config-repo
#searchPaths: foo,bar*
encrypt:
keyStore:
location: classpath:/server.jks
password: letmein
alias: abc
secret: changeme
key: abc
server:
port: 8888
adding this to both eureka server and config client application.yml:
encrypt:
key: abc
Run everything:
Result is same nasty error
So what is wrong is my testing? Thanks for your help
It is my fault:
Changing application.yml to this:
spring:
application:
name: configserver
encrypt:
failOnError: false
keyStore:
#location: classpath:keystore.jks
#password: ${KEYSTORE_PASSWORD:foobar} # don't use a default in production
#alias: test
location: classpath:server.jks
password: letmein
alias: mytestkey
secret: changeme
And then using this command to generate the file resolving the issue completely:
keytool -genkeypair -alias mytestkey -keyalg RSA \
-dname "CN=Web Server,OU=Unit,O=Organization,L=City,S=State,C=US" \
-keypass changeme -keystore server.jks -storepass letmein
Thanks
