Prohashing Mining Pool Forums

Hello all,

I am having some trouble getting started although currently mining via my PC at the moment successfully with GMiner.

I have an AWS EC2 Linux Ubuntu Xeniel, NVidia GPU running BFGMiner. I have tried many pool sites, many algorithms but just never receive any jobs.

Currently using URL:stratum+tcp://prohashing.com:3333, password: a=scrypt. I have tried many others with no success.

My prohashing workers are reported on the dashboard. The one connected to my PC is running away fine, the one connected to my server in AWS is awaiting first share.

The following messages repeat:
[2021-05-06 14:27:56] Network difficulty changed to 176k ( 1.26T)
[2021-05-06 14:27:56] Stratum from pool 0 detected new block

Assuming that it might take a while to receive jobs I left it over night but no success. While the PC picked them up in minutes.

Should I have specific inbound rules to allow for BFGMiner/Prohashing?

Any support would be appreciated.

Kind regards

My understanding of EC2 is that you're trying to mine scrypt with a GPU. If that's true, then scrypt has long since been overtaken by powerful ASICs that are specifically created to outperform GPUs. You won't find any shares with a GPU using scrypt at the default difficulty.

If you want to mine with a GPU, I suggest mining ethash, or etchash if you have a GPU with lower than 4GB of memory.

Thanks Steve, the GPU should have about 8GB of VRAM, I will try and focus on ethash and see if I can pick up some jobs. Thanks
