Connection

How to check my connection?

To test the reachability of our servers, you can use the ping utility. Example of a successfully established ping connection:

ping stratum.braiins.com
PING stratum.braiins.com (172.65.65.63): 56 data bytes

64 bytes from 172.65.65.63: icmp_seq=0 ttl=52 time=29.191 ms
64 bytes from 172.65.65.63: icmp_seq=1 ttl=52 time=59.535 ms
64 bytes from 172.65.65.63: icmp_seq=2 ttl=52 time=21.847 ms
64 bytes from 172.65.65.63: icmp_seq=3 ttl=52 time=56.541 ms
64 bytes from 172.65.65.63: icmp_seq=4 ttl=52 time=28.268 ms

--- stratum.braiins.com ping statistics ---
5 packets transmitted, 5 packets received, 0.0% packet loss
round-trip min/avg/max/stddev = 21.847/39.076/59.535/15.716 ms

If for some reason the ping utility is not available, you can also use Telnet instead. Example of a successfully established Telnet connection:

telnet stratum.braiins.com 3333
Trying 172.65.65.63...
Connected to stratum.braiins.com.
Which server should I connect to?

Only one URL is now used by our Pool. Braiins Pool servers are located all around the world and automatically selected based on your location. For best efficiency we advise stop using location-specific URLs used in the past (e.g. Europe, USA, Canada, Brazil, Singapore, Russia, etc.).

Check Bitcoin Mining Setup for proper miner configuration.

I cannot connect to Braiins Pool. What's wrong?

If your miner is not connecting to our servers please follow these troubleshooting steps:

  1. Check if your HW supports the required hashing algorithm.
  2. Reboot your device.
  3. Double check the miner configuration to make sure that:
    • Your username is spelled correctly (username is case sensitive).
    • There are no white-space characters in your config.
    • You are using the correct pool URL for Bitcoin mining.
  4. Try alternative ports for the URLs (some ports might be unreachable in your region).
  5. Upgrade your device's firmware to the latest version. (Note: it is becoming common for some ASIC manufacturers to lock the SSH in firmware updates, so be careful about this before installing an upgrade.)
  6. Check your network settings, e.g. router security-filtering features.
  7. Check that your ISP is not blocking the relevant port numbers.
Why does my miner have a disabled status?

When you switch off monitoring for a worker its state is reported as Disabled, regardless a fact if it submits some shares or not.

Why do I see a different hash rate on my profile and on my miner?

There is a difference between a nominal hash rate shown in the manual of your mining device and an effective hash rate shown in our system.

For more information please read our Hashrate article here.
