I can't really speak to that. At my own meager 600 kH/sec, I made 2,965 DOGE today mining on the multiport. The multiport was on DOGE 63% of the time (per multipool stats page), which means if I mined DOGE for 24 hours I should have made ~4706 DOGE which is almost exactly (actually a little more than) the estimate that coinwarz gives me for 600kH (4646).
Our fee is 1.5% as stated in OP.

If mining doge on multi port (7777) works, perhaps it's an issue with doge only port (3352) ?
As I explain above, I have only 40k instead of 60k/day..this is a huge difference. And the chart of my hash-rate don't report any problem...the pool receive 7.5Mh -> 60k/day, but I only have 40k.
