How you write the password commands? for me d=64 work
my line looks like this:
a=x11 d=64 p=3.5 w=827 n=d326
and don´t forget, the diff must be power of 2
Thanks mate, works now so simple!! I was using , instead of space. Feel properly stupid now.

No problem it´s not stupid the , you use on a lot of other pools, but prohash is in a lot of config things special, look only the way they use for the ALGO, think it´s the only pool that use the password commands to define the ALGO all other pools use the Stratum.
