      The main difference I see is here:

      you use http://46.4.0.101:19327

      and on your node you use stratum+tcp://cryptogrinder.com:19327

      This means, that you use different protocols between the p2pool server and your miner.

      http://… means getblocktemplate is used

      stratum+tcp:// means the stratum protocol is used.

      The stratum protocol is newer, but also sometimes needs some tuning.
      I don’t know nsgminer, so I can’t tell if it uses the extranonce extenion or not, but extranonce is not implemented on p2pool and therefore leads to errors.

      Can you use http://cryptogrinder.com:19327 for a fast check, if the error rate goes down?

        I tried without stratum+tcp:// but no help… actually I was mining with it before and was fine. Here’s the summary:

        running node locally at home seems fine… no checkblockheader at all…

          can you try with ccminer or cgminer against my pool?.. maybe you could spot some weird stuff…

              I had my sgminer running for 39 minutes and no rejected shares at all.
              Unfortunately I can’t get nsgminer working for neoscrypt on m system

              as you can see there are some rejected shares after an interrupted stratum connection.

              My miner reports a rejection rate of 11.5% and your pool node reports a DOA of ~39%

              Connection interruptions can be caused by the host you are running your p2pool node on, or connectivity problems to the pool node.

                I just compared your p2pool version with the latest one on github, which is

                v15.0-28-g6d59072

                can you pull the latest version, do a ‘git checkout master’

                and restart your pool?

                There are some fixes in the latest version.

                  Stopped my miner now.

                  Final Statictics:

                  I think the reason for the high rejection rate are the interruptions miner to p2pool connection

                          but not sure what was the problem… ?!

                          It was a bug in the adaptive behavior of the p2pool software.

                                Many thanks :)

                                You also helped the community by bringing up the problem and verifying that the problem is fixed in the last p2pool code, so it’s on me to thank you.
