I have an existing page already loaded up on my PC (Chrome browser), and when I hit refresh, it did not complain about the cert.  Looks like a valid cert from GoDaddy.  The error is from my phone on the Lastpass browser.  Chrome on phone is also fine.

Maybe I would get an error on my PC if I deleted my cache.

I hope there isn't a MITM attack...

The active worker count has dropped very sharply but the hash rate is still around the same. I'm starting to wonder if the numbers are being fudged   I know I have a negative tone to my writing but come on. The hash hovers between 50-60 Ph/s and this was with a reported average of about 300,000 workers; we are now down to 56,680 but no real change in the hash Not to mention we no longer compare to F2Pool in the luck aspect. I haven't seen any increase in per share pay so I'm at a lost.

Luck at the Antpool was a  bit low, but it is turning around and coming back!

Stay tuned!

No there is no way how anyone can improve pool luck.

Do you have a failover pool set for your S5?

He explained it all I believe.   Only thing might not be there is 25 is the current amount of BTC you get when solving a single block.

Needless to say google "PPS Bitcoin Pool" this is what Antpool.  After reading that you should understand the payment system.  Go here at bottom to find current luck https://www.antpool.com/poolStats.htm  .  Again read about "PPS Bitcoin Pool" to explain how it works.

A share is a unit of work that your S3 submits to the pool.  The pool uses these shares to calculate how much of the reward you get when the pool finds the block.

That percentage shows you how how many shares it took to solve that block vs the expected amount of shares it should have taken.  In this case, it took 80,219,210,336 shares.  Expected number of shares to solve a block is 47,610,564,513.  It took 168.49% (Bitmain, you might want to check your math on your page since you show 168.47%) of expected shares to solve the block.
