Seems to be a matter of King's safety together with nullmove, Robert Flesher's Zappa Aggressor Dissident e.g. is doing very well here too.

K9 with nullmove switched off and King Safety raised to max. (200):

...and on the same machine K9 did not come to solution after 100 minutes.

Maybe I'll give it one more try with nullmove off only and or King Safety max. only, if I don't need that PC for anything else

It's strange to have to turn off null moves because after some null moves for white, black should see easily the winning sequence ...
