nicehash stratum error

[baaa]

not sure if this is the correct repository, but could not find a bug report for the website, here is the issue:

I have implemented nicehash stratum protocol for a fork of sammys open ethererum pool. Pool successfully passes verification but does not work when I actually create an order. when I use the pool verificator, I can see from the server logs that

mining.subscribe -> mining.notify -> mining.authorize

successfully. But when created an order nicehash never returns back after mining.notify

the parameters my pool is sending for mining.notify are as follows

Id 49
Version EthereumStratum/1.0.0
Result[0].param0 mining.notify
Result[0].param1 92f8a5658ad18a7ef4dad54ae62b529f
Result[0].param2 EthereumStratum/1.0.0
Result[1] eed8
Error Null

pool verificator: 
address: etp.dodopool.com

failing order: https://old.nicehash.com/index.jsp?p=orderdetails&id=4464936&algo=20&l=0

Can you please assist me with the incorrect or missing parameter?

Thanks,
