Hi,
I see. I will release a new version soon with fixes for most known issues.
Can connect to Nicehash using stratum+tcp:// but EtraNonce is not subscribed.
Some people, including me, tried stratum2+tcp//, stratum3+tcp:// and forgot about stratum+tcp:// is because the guide says
'stratum+tcp://' is not required because TT-Miner will automatically detect the correct stratum protocol in use. So when there's a stratum compatibility error, I thought, so if the default (stratum+tcp://) does not work, let me try stratum2, stratum3, etc.
