Connection to remote redis server is reset - redis

Question

Trying the basic set operation on a redis server installed in red hat linux.
JedisPool pool = new JedisPool(new JedisPoolConfig(), HOST, PORT);
Jedis jedis = null;
try {
jedis = pool.getResource();
System.out.println(jedis.isConnected()); //prints true
jedis.set("status", "online"); //gets exception
} finally {
if (jedis != null) {
jedis.close();
}
}
pool.destroy();
Getting the following exception:
Exception in thread "main" redis.clients.jedis.exceptions.JedisConnectionException: java.net.SocketException: Connection reset

How to resolve the issue ?

Answer 1

I had a similar issue. Our production Redis required an encrypted connection over TLS, whereas our test system did not. In production therefore the java.net.SocketException: Connection reset appeared when we tried to use the Jedis connection.
To fix it, use
JedisPool pool = new JedisPool(new JedisPoolConfig(), HOST, PORT, true);
for connections that require TLS.
