D3 connection issues

Post by T_Power » Thu Dec 28, 2017 4:30 pm

Hello all,
Having issues with my Antminer D3 and PH pool.
Been here for about a week, and every day the pool appears to go DEAD according to my miner for between 10 min some times, and 60 min other times.
It goes dead about 5 to 10 times a day. :(
Worker history agrees with my miner DEAD time, PH is pool 0 in my miner config, and the miner then falls over to pool 1.
When this happens, and PH becomes ALIVE again, my 2hr share estimate starts at 0 again, seriously affecting my payouts...
My setup is:-
URL = prohashing.com:3333
Worker = "My Username"
Password = a=x11 w=1220 p=0.08 n=Cameron3

Any help will be appreciated.
Regards,
Tim

you are running Blissz firmware. it switches pools every couple hours for you to mine his DEV fee. change your firmware back to the latest bitmain version unless you think the cost savings for power is worth the dev fee.


if you are not running Blissz firmware, is supernova your second pool.

I am asking because that log looks alot like blissz firmware switching pools

this is from server restart. it is my logs also

but no other log entries seen on any on my miners except one im testing Blissz firmware, log shows i also connected to supernova about same time as you and since i don use supernova at all i know that it is his dev fee kicking in

Hello again greaseman316,

Only got one D3 miner, received mid November.
Never flashed the unit or upgraded to new firmware.

If the D3 mines to other pools, I don't have issues with DEAD pools like i'm having now.
I really want to sort this out, I like PH's ability to pay out in any coin. :)

Regards,
Tim

that is weird to say the least. maybe try adding d=256 or d=128 to your password line.

i have 1 stray miner that just wont run right unless i use static difficulty. if that dont help with the disconnects try reflashing your firmware.

other than the restart today i been going non stop for almost 3 days now without a hiccup

Hello greaseman316,

I think your idea of a static difficulty might just help.
Why I say that, is my Hashrate History is all over the place on this pool .(5G -> 60G)
I'll be setting it to 128 for today and see what happens, thanks.

Regards,
Tim

Hello all,

A slight update on my Antminer D3 and PH pool.
By setting the difficulty to static (d=128) the miner seems a lot more stable, and has been mining for just over 5 hours now without seeing the pool as DEAD. :)

It has now climbed from a starting hashrate of 8.2 GH/s to an average hashrate of 20.8 GH/s after 5 hours 14 min, and to a 2hr share estimate of 264.
Will continue to monitor.
Regards,
Tim
