Ok, this is fu**ing ridiculous ... you need to remove that shady private connection to your website:
[WARN] [2018-02-13T05:13:02Z] Failed to read from the network: Get : dial tcp: lookup api.bminer.me on 192.168.1.1:53: read udp 192.168.1.22:42393->192.168.1.1:53: i/o timeout
Your server went down and the miner stopped mining. This is seriously not cool. Besides being shady AF, you are also costing us money. My miners just wasted 1h ...
This communication is not the root cause of the mining hang. Mining should continue even if you cannot connect to api.bminer.me. It is very likely caused by the reconnection issue that is already fixed in 5.4.0. Could you try 5.4.0?
