I have the same issue. I am mining with GPU and left my wallet with builtin miner running for days. Everything seemed good, just not finding any blocks. I decided disable GPU mining in the wallet and activated the command-line beam miner. It’s connecting with the pool and the performance is approx. 8 sol/s. A whole week later, no blocks. I don’t get it. I went and double-checked my wallet address. It looks right and the address never expires. I’m really confused here. As far as I know, everything is working as it should. I’m just not resolving any blocks. I did notice that my difficulty has been going up. It starts at around 100, but now it’s at 307. Help?
