You should have a local SMTP domain name that will contact the mail server and establishes a new connection as well you should change the SSL property in your programming below 

<pre><code>javax.net.ssl.SSLException: Unrecognized SSL message, plaintext connection

 props.put("mail.smtp.socketFactory.fallback", "true"); // Should be true

I had to force jvm to use the IPv4 stack to resolve the error. My application used to work within company network, but while connecting from home it gave the same exception. No proxy involved. Added the jvm argument 
 <code>-Djava.net.preferIPv4Stack=true</code> and all the <code>https</code> requests were behaving normally.

 return AmazonDynamoDBClientBuilder.standard()
 .withCredentials(
 new AWSStaticCredentialsProvider(

blocks|key|851644|text|正如EJP所说，这是由于对非https协议的调用而显示的消息。如果您确定它是HTTPS，请检查您的绕过代理设置，如果是，请将您的webservice主机url添加到绕过代理列表中。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|851645|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

As EJP said, it's a message shown because of a call to a non-https protocol.
If you are sure it is HTTPS, check your bypass proxy settings, and in case add your webservice host url to the bypass proxy list

HERE A VERY IMPORTANT ANSWER:

You just change your API URL String (in your method) from https to http..
This could also be the cause:

<pre><code>client.resource("http://192.168.0.100:8023/jaxrs/tester/tester");
</code></pre>

instead of

<pre><code>client.resource("https://192.168.0.100:8023/jaxrs/tester/tester");

blocks|key|635423|text|另一个原因可能是“访问被拒绝”，也许你无法访问URI并收到内部网络访问的阻塞响应页面。如果您不确定应用程序区域是否需要防火墙规则，请尝试从终端、命令行进行连接。对于GNU/Linux或Unix，您可以尝试运行以下命令，并查看结果是否来自阻塞规则或真正的远程地址：echo+%7C+nc+-v+yazilimcity.net+443|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|635424|entityMap^0|3N|W|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|K|8|@]|D|@]|E|$]]]|G|$]]

Another reason is maybe "access denided", maybe you can't access to the URI and received blocking response page for internal network access. If you are not sure your application zone need firewall rule, you try to connect from terminal,command line. 
For GNU/Linux or Unix, you can try run like this command and see result is coming from blocking rule or really remote address: <code>echo | nc -v yazilimcity.net 443</code>

I think this is due to the connection established with the client machine is not secure. Is there any way to configure the local machine or ports in order to connect to the remote https server?
