on original minergate gui software all working fine.

[berezinevgeniy]

[dimkers]

I haven't.

[berezinevgeniy]

• POOL 128tx exploit #1 stratum+tcp://xmr.pool.minergate.com:45700 variant 1
  why variant 1 has been choosen. variant:2 set at config.

[dimkers]

can you try on other pool(not minergate)?

[berezinevgeniy]

• POOL 128tx exploit #1 spool.minexmr.com:4444 variant 2

The bug is in this line, just change to Variant_2 and recompile the code!

[dimkers]

YES!
change in code
m_algorithm.setVariant(m_port == 45700 ? VARIANT_1 : VARIANT_0);
to
m_algorithm.setVariant(m_port == 45700 ? VARIANT_2 : VARIANT_0);
recompil and miner work!

You can try with IP address instead domain name (xmr.pool.minergate.com).

[xmrig]

I will make new releases as soon as possible, right now I can't, unexpected power outage in my location. As temporary solution use IP address instead of domain name as mentioned above.
Thank you.

[xmrig]

@0xc0d32 I merge your PRs, as quick emergency fix it ok.
