Stratum+tcp Prefix Mistakes on Bitmern Solo (Bitaxe Fix)

Your Bitaxe refuses to connect, stays Connecting forever, or rejects the stratum string — and the host field still contains stratum+tcp://, stratum://, or even https://. The rest of the string may look “right,” but many firmwares treat the host box as a bare hostname, not a full URL. Paste the scheme into that box and the session never opens cleanly.

If stratum+tcp prefix mistakes are blocking your Bitaxe on Bitmern Solo — firmware rejects the host, Connecting never becomes Authorized, or you pasted stratum+tcp://btc.bitmernsolo.com:3132 into a host-only field — run an ordered checklist: bare host btc.bitmernsolo.com, BTC easy-start port :3132 (never treat :3102 as the Bitaxe / home default), username WALLET.worker, password x, then retest a new session. This post is not the general stratum-url-mistakes lane, the wrong-coin-endpoint lane, the first-connection-checklist lane, or the stuck-connecting lane — and Current Effort is not a find guarantee.

This is the stratum+tcp-prefix lane. Wrong host/port string without a scheme story: stratum URL mistakes. Greenfield full connect string: first connection checklist. Coin host mismatch: wrong coin endpoint. Stuck on Connecting without a prefix root cause: stuck connecting. Password field confusion: stratum password x.

Bitmern Solo is solo infrastructure: flat 1% fee on finds only, you keep 99%. Fee context stays light here — the job is to stop prefix paste errors from killing the session.

Prefix mistakes ≠ URL mistakes ≠ wrong coin ≠ first connection ≠ stuck connecting

Five patterns get mixed up:

  1. Stratum+tcp prefix mistakes — the host field includes a scheme (stratum+tcp://, stratum://, https://) that firmware does not want there. That is this post.
  2. Stratum URL mistakes — wrong host, typo, or bad port string without a scheme-in-host story. Use stratum URL mistakes.
  3. Wrong coin endpoint — pointed at another coin’s host while reading the BTC tab (or the reverse). Use wrong coin endpoint.
  4. First connection checklist — greenfield full string from zero. Use first connection checklist.
  5. Stuck connecting — Connecting forever for broader reasons after the string looks clean. Use stuck connecting.

Do not invent a Bitmern Solo “must use prefix X on all firmwares” product guarantee, a universal URL-vs-bare-host matrix sold as an SLA, or a claim that Current Effort predicts finds. Product facts that matter for retest: BTC host btc.bitmernsolo.com, easy-start port :3132, username WALLET.worker, password x. Some firmwares accept a full stratum+tcp://… URL in one combined field; others want bare host + separate port. Follow your firmware’s fields — do not force a scheme into a host-only box.

What prefix mistakes usually look like on a Bitaxe desk

Common desks:

  1. Host field shows stratum+tcp://btc.bitmernsolo.com — scheme pasted into a hostname box.
  2. Port already set to 3132, but Connecting never clears — host still carries stratum+tcp:// or stratum://.
  3. Firmware rejects / invalid pool URL — combined string pasted into the wrong field.
  4. https://btc.bitmernsolo.com in the host box — web scheme where stratum wants a host or a stratum URL.
  5. You “fixed” port to :3102 while chasing the reject — easy-start for Bitaxe / home BTC is :3132, not :3102.
  6. Username is bare wallet with no .worker — every retry looks like a new broken session after you clear the prefix.
  7. Password is blank / password / random — see stratum password x; Bitmern Solo expects x.
  8. You already read general URL-mistakes posts — you need the ordered prefix-only fix.

Separate these from coin-host mismatches (wrong coin endpoint) and from greenfield first-connect walkthroughs (first connection checklist).

Ordered diagnose-and-fix checklist

Run top to bottom. Stop when firmware holds a clean Authorized / Subscribed session, the matching coin tab shows the worker, and accepts can move — without inventing a “prefix required on every firmware” product SLA.

1. Read the fields your firmware actually exposes

Symptom: You paste a full URL into a host-only box, or a bare host into a “full stratum URL” box.

Fix: Open AxeOS (or your miner UI) and note whether you have (a) one combined URL field, or (b) separate Host + Port. If Host is separate, the value should be the bare hostname — not a scheme.

2. Strip schemes from host-only fields

Symptom: Host contains stratum+tcp://, stratum://, or https://.

Fix: For a host-only field on BTC easy-start, use exactly:

btc.bitmernsolo.com

Port field:

3132

Never treat :3102 as the Bitaxe / home default. If your firmware uses one combined URL field and its docs show a scheme, use:

stratum+tcp://btc.bitmernsolo.com:3132

— but only in that combined field. Do not invent a global “always include the prefix” Bitmern product rule for every UI.

3. Confirm BTC easy-start port before you chase DNS myths

Symptom: You “fixed” the reject by flipping to :3102 or a random foreign port.

Fix: BTC easy-start for Bitaxe / home is :3132 on btc.bitmernsolo.com. Re-paste carefully, then open a new session after save/apply.

4. Confirm username and password format

Symptom: Username is bare wallet, wrong worker label, or password is not x — so every prefix fix still fails auth.

Fix: Username:

WALLET.worker

Password:

x

Wallet must be registered for that coin on Bitmern Solo. Password context: stratum password x.

5. Separate prefix mistakes from general URL typos

Symptom: Host is bare but misspelled (btc.bitmernsola.com), or port is empty / swapped.

Fix: That is stratum URL mistakes. Stay here only when the durable story is a scheme stuck in the host field (or a combined URL pasted into the wrong boxes).

6. Separate prefix mistakes from wrong-coin endpoints

Symptom: Host is clean for BTC but the miner is on another coin’s endpoint while you watch the BTC tab.

Fix: Use wrong coin endpoint. Prefix hygiene does not fix a coin mismatch.

7. Separate prefix mistakes from first-connection greenfield

Symptom: You have never completed a clean first connect and need the full walkthrough.

Fix: Use first connection checklist. Return here when the only remaining bug is scheme-in-host.

8. Open the matching coin tab before you declare failure

Symptom: You stare at the wrong coin tab after a string change and conclude Bitmern Solo never saw the worker.

Fix: Open the same coin the miner is pointed at. Confirm the worker under the expected WALLET.worker label. If Connecting persists with a clean bare host + :3132, also skim stuck connecting. Card reading stays in the dashboard guide.

9. Prove the session — not a luck promise

After a clean apply + new session with schemes stripped (or correctly placed in a combined URL field):

  • Firmware holds Authorized / Subscribed (or equivalent)
  • Matching coin tab shows the worker under the expected label
  • Fresh accepts can move while the board hashes
  • You are not treating Current Effort as a find clock

Current Effort is an ops signal — not a find guarantee. Guide: dashboard workers / shares / effort.

10. Soft fee reminder only after the session holds

Fee reminder only if you need it: flat 1% on finds; you keep 99%. Clearing a prefix paste error is an ops win, not a fee event.

When URL mistakes, wrong coin, first connection, or stuck connecting is the real story

If the host is already bare but wrong, use stratum URL mistakes. If the coin host does not match the tab, use wrong coin endpoint. If you need the greenfield full string, use first connection checklist. If Connecting persists after a clean prefix fix, use stuck connecting. Password-only confusion: stratum password x.

What this post will not invent

  • No “must use stratum+tcp:// on all firmwares” product guarantees
  • No claim that :3102 is the home Bitaxe default (easy-start is :3132)
  • No luck formulas, dollar EV, or find-time promises from Current Effort
  • No fabricated universal URL-vs-bare-host SLA sold as Bitmern Solo policy
  • No competitor fee comparisons

Fee reminder: flat 1% on finds; you keep 99%. A clean host field + correct port is desk hygiene, not a luck product.

Quick retest sequence after a prefix or field change

After you strip a scheme, move values between Host/Port, or correct username/password, do not stare at one stale Connecting line forever. Use a short retest loop:

  1. Confirm BTC easy-start still btc.bitmernsolo.com + :3132 (or one combined stratum+tcp://btc.bitmernsolo.com:3132 if that is your firmware’s single URL field).
  2. Confirm username WALLET.worker, password x.
  3. Save / apply and reboot so firmware opens a new session.
  4. Open the matching coin tab — not a neighbor tab.
  5. Watch for Authorized / Subscribed and a worker row — not Current Effort as a find promise.

If the host is bare but still wrong, leave for stratum URL mistakes. If Connecting persists with a clean string, leave for stuck connecting.

Common stratum+tcp prefix mistakes to avoid

  1. Pasting stratum+tcp:// into a host-only box — strip the scheme; keep bare btc.bitmernsolo.com.
  2. Treating :3102 as “the Bitmern port” — easy-start for Bitaxe / home BTC is :3132.
  3. Skipping .worker — username format matters for attribution after every reconnect.
  4. Using a non-x password — Bitmern Solo expects password exactly x.
  5. Reading the wrong coin tab after a string change — prove the worker on the matching tab.
  6. Inventing a universal prefix SLA — follow the fields your firmware exposes; do not demand a product guarantee the desk never published.
  7. Blaming Bitmern Solo before reading the host field — confirm scheme-free host + :3132 first.

None of these mistakes invent a prefix SLA. They only restore a path from a polluted host field to a real session and proven accepts.

How this checklist fits the ops library

Start here when a scheme in the host field is the active failure. Move sideways when the symptom clearly belongs to another lane.

Soft next step

Lock BTC easy-start bare host btc.bitmernsolo.com with port :3132 (or one combined URL only if your firmware’s single field requires it), keep WALLET.worker with password x, open a new session, then confirm Authorized / Subscribed plus a worker row — before you chase luck myths or invent a prefix SLA.

FAQ

What should go in the Bitaxe host field for Bitmern Solo BTC?

Bare hostname btc.bitmernsolo.com when Host and Port are separate. Port 3132. Use a full stratum+tcp://… string only if your firmware’s single combined URL field documents it.

What BTC port should a home Bitaxe use?

:3132 on btc.bitmernsolo.com. Never treat :3102 as the Bitaxe / home default.

What username and password does Bitmern Solo expect?

Username WALLET.worker (wallet must be registered for that coin). Password exactly x.

Is a prefix mistake the same as a stratum URL mistake?

No. General host/port typos belong in stratum URL mistakes. Use this post when a scheme is stuck in the host field (or a full URL is pasted into the wrong boxes).

Does Current Effort mean I am about to find a block?

No. Current Effort is an ops / attribution signal — not a find guarantee. See the dashboard guide.

Where do I confirm the fix on Bitmern Solo?

Matching coin tab → worker row → firmware holds Authorized / Subscribed → fresh accepts when the board hashes. Guide: dashboard workers / shares / effort.
