Stratum difficulty 25000

Started mining (Electroneum) yesterday, everything was going good.  Turned off CCminer for a bit today, and turned it back on.  Stratum difficulty was set to 25000 and I'm no longer getting the accepted: 1/1 with (yes!) at the end of the string. Yesterday it was happening very, very fast.  Now it is few and far between.

Every once in a while I'll get a single or a few (3) H/s to accept, then back to more of the info posted above.

Can anyone please explain what is going on?
