Hashing & Connectivity Status

Overview

Each worker in Braiins Manager has two distinct attributes to help users understand performance and connectivity:

Hashing Status – Indicates miner performance and efficiency
Connectivity Status – Indicates whether the miner can be reached and remotely controlled

Hashing status shows how well the miner is performing based on its real-time hashrate and energy efficiency.

Hashing Status	Condition	Meaning
Hashing	Real hashrate > 0 AND efficiency (J/TH) within 10% of nominal	Miner is hashing with expected efficiency
Inefficient	Real hashrate > 0 AND efficiency (J/TH) > 10% above nominal	Miner is using more power than expected
Idle	Real hashrate = 0	Miner is powered but not hashing
Maintenance	Manually set into maintenance	Miner is intentionally entered into maintenance
Unknown	Missing data (e.g. no hashrate or power readings)	Status cannot be determined

Connectivity status shows whether Braiins Manager can communicate with the miner.

Connectivity Status	Description
Online	Miner is connected and responding normally
Agent Offline	Braiins Manager Agent is not responding
Offline	Miner is unreachable or disconnected
N/A	Miner is under maintenance
ERROR (e.g. `TIMEOUT_ERROR`)	Miner is online but encountered a specific network or system error

If a miner shows a specific connectivity error instead of "Online", use the table below to diagnose and fix the issue.

Error Code	Meaning	Suggested Action
`TIMEOUT_ERROR`	Miner did not respond in time	Check network, try to ping miner's IP from the Agent's server, reboot miner
`FETCH_ERROR`	Failed to retrieve data from miner	Check if miner is accessible via GUI and if did not change the firmware
`JSON_PARSE_ERROR`	Malformed response	Check if the firmware on your miner has changed. If needed, use the Change Firmware action
`ETIMEDOUT`	Connection timed out	Check latency, routes, or DNS
`EHOSTUNREACH`	Host unreachable	Inspect subnet or switch
`ECONNRESET`	Connection closed unexpectedly	Check miner logs or power cycle
`ECONNREFUSED`	Miner rejected the connection	Ensure miner API is enabled
`AUTH_ERROR`	Authentication failed	Verify miner's credentials
`PARSE_ERROR`	General parse failure	Same as JSON error
`ENETUNREACH`	Network unreachable	Check routing, gateway
`ECONNABORTED`	Connection forcibly closed	Restart agent or miner
`ENOBUFS`	No buffer space available	Restart agent or tune system buffers
`LOCAL_ADAPT_ERROR`	Network interface issue	Check agent network config
`EACCES`	Permission denied	Run agent with proper permissions
`ERR_BAD_REQUEST`	Malformed HTTP request	Check agent version and miner firmware
`CERT_HAS_EXPIRED`	TLS certificate expired	Renew cert or disable HTTPS (if safe)
`EADDRNOTAVAIL`	Local IP unavailable	Review IP config or interface bindings

If Connectivity Status is Agent Offline or any ERROR, then Hashing Status will show as Unknown.
Removed status is deprecated — removed miners are no longer visible in the UI.

You can view the Hashing Status and (optionally) the Connectivity Status in the Workers List table:

Workers list showing Hashing and Connectivity Status

You can also find the statuses on the individual worker detail page under the "About Worker" section:

Worker detail page showing Hashing and Connectivity Status

Hashing Status and Connectivity Status are displayed side by side for clarity.
