Hi, can you send a screenshot? I'll pass it on to the developer.
Until we saw such a problem, our test miners worked well.
I started this miner when I was at 17 shares on the website. It still says 17 shares and I've got 5 on the PC.
https://ibb.co/jGbYURPool diff is 90. With a "small" hash power you may wait a long time (several minutes or hours) to get a single share at that diff. So we also display shares at diffculty 81.
So you can see that the mining Miner works well. You can also compare the performance of eggminer and bis-pool miner by the number of тshares @ 81 per hour or minuts.
