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

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.

Does this SSL error come on the client-side or Identity Server side? — Piraveena Paralogarajah
If the error is coming from the application side, Have you imported Identity Server's public certificate into the application's trust store(here it is custom.jks )? — Piraveena Paralogarajah
It comes from Indentity Server side. @PiraveenaParalogarajah — Aldo Inácio da Silva
I've imported Identity Server's public certificate custom.jks into the application — Aldo Inácio da Silva

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");
}
