Hi, I'm a newbie trying to mine Ethereum on MPH and I've encountered some problems.

I have tried Excavator (from latest NiceHash) and Ethminer (v. 0.13.0 from https://github.com/ethereum-mining/ethminer/releases).

The miner succesfully connects to MPH, authenticates with my user/workername and it seems to start mining. It's periodically fetching new jobs and Ethminer shows the proper hashrate. However, I'm not getting any shares, MPH dashboard shows 0 MH/s hashrate and I'm not getting any coins to my balance. Only thing that updates on the MPH page is the workers list (with 0 KH/s there) so I know the miner is communicating with MPH at least on some level.

Some examples of what I've tried:
ethminer.exe -G -S europe.ethash-hub.miningpoolhub.com:20535 -O username.test
ethminer.exe -U -S europe.ethash-hub.miningpoolhub.com:20535 -O username.test:x -v 9 --cuda-parallel-hash 4 --cuda-grid-size 4096

For excavator, I used the IP of europe.ethash-hub.miningpoolhub.com and port 20535.

Images (I'm testing on my desktop so the low hashrate is normal but it's the same problem on my mining rig, I just don't want anymore downtime there):

Any help would be greatly appreciated. Mining Ethereum on NiceHash works fine. Mining ZCash on MPH works fine. Ethereum on MPH doesn't. I'm puzzled.
