The pool hasn't found a block in about 8 days, but theoretically it should find ~1/day at the current hashrate and Monero's current difficulty. It's not a uniform distribution though so you won't always see it in that regularity. If you look at the blocks found page you'll see a history of findings and difficulty associated with it. It looks like the pool may have been unlucky for a little while, but that's not to say it won't find 5 blocks in the next hour. You'll be rewarded as long as you continue to contribute shares to each round. If you stop now you will still be rewarded for shares contributed in the current round. If you're looking for a more consistent payout then you should find a more populated pool, otherwise there is a certain degree of luck associated with smaller pool/solo mining. Personally I stick to smaller pools to help stave off a 51%.

For reference I've been mining CLO on coinfoundry but recently switched back to ETC with the site going down for some pools. CLO was a smaller pool, too. There could be multiple days in a row with no blocks found, or 5 in a day, just like I described above. 

My connection strings appear appropriate, it also looks like someone is still able to mine on the pool.
