java jedis (redis) cannot connect

I'm trying to connect to Redis using Jedis in my java application. I'm instantiating a JedisPool object, and when I get the resource, it throws an exception saying it cannot return the resource. What is weird though is if I just instantiate a Jedis object, it connects without problems, and I can change data.

Here's my RedisDatabase class:

package me.joeleoli.proxylink.database; import me.joeleoli.proxylink.ProxyLink; import redis.clients.jedis.Jedis; import redis.clients.jedis.JedisPool; public class RedisDatabase { private JedisPool pool; public RedisDatabase(String host, int port, String password) { ProxyLink.getInstance().getLogger().info("Attempting to establish Redis connection " + host + ":" + port); this.pool = new JedisPool(host, port); try (Jedis jedis = this.pool.getResource()) { if (password != null && !password.equals("")) { jedis.auth(password); } jedis.select(0); jedis.close(); } } public JedisPool getPool() { return this.pool; } }

Here's my error:
