Title: Why would pools show DEAD only on one miner? Post by: vrocco on September 02, 2017, 01:11:22 AM I just got two L3+ and I am having a heck of a time keeping them both mining at the same time. Both connected to a good switch and have connectivity to the internet. I can verify this through the network diagnostics in the web UI.
However, one will be mining and show my primary pool as "ALIVE" while at the same time, the second one shows it "DEAD". Sometimes all three pools will show "DEAD" on one while the other is happily mining away. I'm using fairly stable pools (yes, I know prohashing has had some problems, but that's why there's two backups): NiceHash Prohashing Litecoinpool Pools and users are configured correctly and I know this because at some point, each miner has been connected to each pool. However, I'm having a very hard time getting them both to stay connected to at least one pool for any extended period of time. Any suggestions for configurations? I have tried manually setting the DNS to Google's (8.8.8.8) and that didn't seem to make any difference from my ISP's DNS. And yes, I have made sure my ISP allows the required ports. As I said, they have both connected to all pools at some point. Thanks for any help you can give. Bitmain support is useless. I've had a ticket open 24 hours now and no one has even acknowledged it. I mean, I guess you don't have to provide support if people will just keep buying your shitty products. Title: Re: Why would pools show DEAD only on one miner?

if you have 2 psu's you could flip them and see if problem follows the psu. Title: Re: Why would pools show DEAD only on one miner? Post by: vrocco on September 02, 2017, 03:34:42 AM The PSUs are the Bitmain APW3++ and I did try switching them, but the machines perform the same with either PSU.
The other really annoying thing is that every time all the pools eventually go "DEAD", I try restarting the L3+ (because I have let it sit for over an hour and they never come back to ALIVE on their own). When I restart, the HW version in the Overview screen shows "Socket connect failed: Connection refused". They will often sit like this for over an hour before they actually start to mine again. I see they are running DropBear sshd. I'm comfortable in linux if I need to configure something from the shell. I just thought these things were supposed to be a pretty simple plug and play type miner. Title: Re: Why would pools show DEAD only on one miner?

If you have an ASUS router with firmware that includes the TrendMicro "Site Protection"........TURN IT OFF!!
For some reason it doesn't like stratum connections but I guess every so often some were getting through for a bit before getting blocked. As soon as I turned that "feature" off, my miners connected and all my pools show as ALIVE. Back to mining! Thanks for the suggestions. Title: Re: Why would pools show DEAD only on one miner?
