hi. Does anyone have the same problem on bibotel pool?
I get this:

[2017-11-05 23:31:33] Stratum difficulty set to 1
[2017-11-05 23:32:03] stratum_recv_line failed
[2017-11-05 23:32:03] Stratum connection interrupted

I use cpuminer-opt on Ubuntu Vps.
How I start to mine solo? Please some small tutorial?! Thanks
