I tried those and 25 and it's not working.

Same here, all dead - Antpool not working. Moving to Kano.

And why is that?

Anyone missing LTC payment for 1st and 2nd april when Antpool was getting upgraded on 31st March ?

Although I applaud both of your for switching to a pool that share transaction fees, I'm curious why you did not go to Kano.is?  Slushpool charges 2%, Kano charges 0.9%.  Variance is higher on Kano, but getting better by the day.  UI isn't as slick, but for me, profit is what mattered.  Kano community is great (just check the Kano thread in this section).  There is a fairly steep ramp-up for full payment, but that is just a delay, not a penalty (e.g. if you left, you would continue getting paid as you "ramped down" at the same rate you "ramp up".).

U have detailed numbers of this?

You can start here:  https://en.bitcoin.it/wiki/Comparison_of_mining_pools

The two key aspects are:  Fee percentage (lower is better) & transaction fees being shared

During the boom last December, transaction fees topped 40% of the block reward.  That means pool operators that did not share those fees got rich off their miners work.  

After that, fee percentage rules - if you pay less, you earn more.  Pretty simple.

It gets a bit more complicated when you go down to the next level.  PPS is straight forward, but high risk for the pool operator, so their fees typically range about 4%.  PPSLNS (and various variations) pay when the pool gets a block.  That raises your variance (how regular your payments are), but allows for a lower fee since the pool operator is taking less risk.

Then there is size.  Mining is typically a long term endeavor, but that doesn't mean you might be happy with getting a big payout once a month.  If the pool is too small that is the risk (or even less often for some rather small pools).  Pools like Slushpool typically find dozens of blocks a day, so the payouts are pretty smooth.  Kano sized pools find a few blocks a week - not bad.  Over a long enough time period, that aspect should blend out to be the same for everyone (presuming they find blocks on a reasonable schedule - not once a year!).  Remember:  If the pool you select is small, your payout frequency may be long, but the amount will be bigger - given everything else is equal (fees, transaction fee sharing, etc).

I should also point out that any pool claiming to pay more than 100% is getting those rewards from somewhere.  If you see that, read the fine-print.  Pools are not free to run or maintain, they need to charge something to do so unless they are very very small and running in someones basement.  Nothing wrong with that, but your not likely to get the best support, nor will the pool be able to grow much, with such an endeavor.  For instance, one recent pool is advertising 105% payout.  If you read the fine print, that payout is guaranteed so long as the transaction fees are AT LEAST 10% of the block reward.  The 105% simply referred to the block reward, not the combined block + transaction reward.

Only if you like to gamble.  Even Slushpool has good weeks and bad weeks.  Its why their webpage displays their 250 block "luck" - since that should always be close to 100%.  I've seen plenty of times when the other stats there were well below 100%.

Likewise, if you look at the KanoPool block stats, their 500 and alltime average are around 100%, all stats under 50 blocks are well over average, the others are below.

This is not a game to be played for "a week or 2".  

Do not confuse "luck" with "fate" - one looks backwards, the other forward, and they are only randomly in sync.  Its like saying "I predict that half the time you flip a coin it will come up heads" and saying I'm good predictor for future things.
