On Tiny Pool every 10 minutes happens this:

[2018-02-19 12:05:50] Stratum connection failed: Failed to connect to tiny-pool.com port 8333: Connection refused
[2018-02-19 12:05:50] ...retry after 30 seconds

Does anybody have that problem to? This affects the award (from 0.0544% to 0.0368%)+a lot of cycles of cooling-heating gpu.
