1  Bitcoin / Hardware / Re: Official FutureBit Apollo BTC Software/Image and Support thread on: July 16, 2021, 08:25:37 AM
Hello

I'm having some trouble getting my Apollo BTC (Full version) to connect/mine successfully to a pool.

Short version : Hash board starts fine but Pools remain inactive (also on local display) , logs indicate connection success but also "POOL_ERROR ::: Exception: Subscription timed out"

If someone has experienced this error I would love to hear what might be wrong Smiley


Have you tried reflashing the SD Card?

Yes - Tried reflash SD Card +boot without the ssd initially to keep the node from having to resync but as this resulted in the same behavior, it was tried with the ssd but the result is the same sadly even with the 'wipe' of the ssd

Update ---

Managed to get it working with a vpn provider (nord) so it might just be overzealous ISP providers.


Yea looks like your ISP was block share submissions to the pool. Thats super weird and concerning...what ISP/country are you in?

TDC+Telenor/Denmark _BUT_ i need to do more testing before i can confidently throw the blame at them.

Just need to look at the Stratum protocol - With a live connection i now have a baseline Smiley

-- Long version --

Apollo BTC - Full version
Version: d23145d
All defaults - Only pool URL set
Wired internet, tried different ISP connections.
Reflash of sd-card tried.

Node sync : OK , 15+ Connections

Tested with:
  • stratum.slushpool.com:3333
  • eu.stratum.slushpool.com:3333
  • sha256.poolbinance.com:8888 + other ports
  • eu.ss.btc.com:1800 + other ports

( prefixing stratum+tcp:// or not does not seem to matter : -host args always without for futurebit-miner )

  • account+worker name verified in the pool frontend.
  • All pools name:port respond to a simple telnet test, tcpdump show some traffic
  • Regardless of pool the log from the running screen indicates that a connection is made but also an error:

Example :

process args : futurebit-miner -comport /dev/ttyS1 -ao_mode 1 -host eu.stratum.slushpool.com -port 3333 -user ginzu.worker1 -pswd x -brd_ocp 48 -osc 30
