WSO2-IS 5.11.0 - Client SCIM - Received fatal alert: certificate_unknown - ssl-certificate

Question

I'm trying to make a request to create a new user in WSO2 Identity Server but I can't connect to the api:

I've already imported my certificate in client-truststore.jks.
Steps:
1-) keytool -genkey -alias custom -keyalg RSA -keysize 2048 -keystore custom.jks -dname "CN=<"wso2-is-ip">, OU=Home,O=Home,L=SL,S=WS,C=LK" -storepass wso2carbon -keypass wso2carbon
2-) keytool -export -alias custom -keystore custom.jks -file custom.pem
3-) Import certificate in /wso2is-5.11.0/repository/resources/security/
keytool -import -alias custom -file custom.pem -keystore client-truststore.jks -storepass wso2carbon
4-) Check if was imported:
keytool -list -v -keystore client-truststore.jks -alias custom -storepass wso2carbon -keypass wso2carbon
Java application:
protected void setKeyStore() {
System.setProperty("javax.net.ssl.trustStore", "custom.jks");
System.setProperty("javax.net.ssl.trustStorePassword", "wso2carbon");
System.setProperty("javax.net.ssl.trustStoreType", "JKS");
}
protected void submit(HttpMethodBase method) throws IOException {
HttpClient httpUpdateClient = new HttpClient();
// **************************Erro SSL*******************************
int responseStatus = httpUpdateClient.executeMethod(method);
// **************************Erro SSL*******************************
String response = method.getResponseBodyAsString();
System.out.println("/******SCIM response status: " + responseStatus);
System.out.println("SCIM response data: " + response + "******/");
}
Am I missing anything?
PS: WSO2-IS is running on a docker environment in development environment and I'm trying to connect from local machine.

I've used the certificate that comes with WSO2 IS in my application and it worked.
wso2is-5.11.0/repository/resources/security/wso2carbon.jks
protected void setKeyStore() {
System.setProperty("javax.net.ssl.trustStore", "wso2carbon.jks");
System.setProperty("javax.net.ssl.trustStorePassword", "wso2carbon");
}
