HELP: Ethminer disconnects after few hours.

[gameboy366]

For the past few days my ethminer (on HiveOS) disconnects after a few hours of mining. No matter what coin I mine, which pool I choose. After I restart the miner it continues for few hours.

I am not sure if this matters but I think it started when I started mining ETC a few days ago. (Now I am back to ETH)

Error looks like this :

Could not connect to stratum server asia1.ethermine.org:4444, Operation canceled

Disconnected from asia1.ethermine.org

Retrying in 3...
Not-connected
Retrying in 2....
Retrying in 1....

It keeps on repeating the same thing until I restart ethminer. Help.

It definitely looks like a network connectivity error. This happens to me when the pool is down for whatever reason. But if it happens consistently for various pools, than you should look elsewhere. Some suggestions to locate where the error is: 1. try changing the miner or changing the parameters of the miner and 2. try without overclocking if you have any in place.

I had the same issue and was a DNS error, I recomend you to use the file "epools.txt"( read the bitcoin post to see how to use it) and put pools of the other sites:  asia1.ethermine.org, eu1.ethermine.org, us1.ethermine.org and us2.ethermine.org
