Public Pool Canaan Avalon Nano 3 Issues

General Discussions
1

Having some issues with Public Pool I have had a Bitaxe Super and a Nerd Miner running off it with no issues always displays the hash rate. Recently picked up a Canaan Avalon Nano 3
it connects to the pool and will display the hash rate randomly and sometimes just disappears from the Public Pool page. However, the Public Pool Hashrate chart is correct showing 3.0-3.5 TH/s and I know my Nerd and Super aren’t doing that alone, lol. If I login the miners web interface the uptime is good and hardly any rejected… Not sure what this could be.

Does this miner or cgminer have any known issues with this version of Public Pool? If I connect to web.public-pool.io it will work fine and always show the hash rate? Is this an older version on Umbrel?

I have uninstalled and reinstalled Public Pool, Restarted Node, Defaulted the Nano 3 always the same result.

Thanks :slight_smile:

Hi there, were you ever able to get to the bottom of this? I experiencing the exact same things as you. I know the nano is hashing but it drops off constantly, seems it cant keep a connection long enough to show any hashrate in public pool on my node? Also it’s not cgminer as I have a gekko compac f that uses it and it connects fine alongside my bitaxes as well.

Did you get to the bottom of this? I’m having the same issue. It seems the nano’s cant stay connected long enough so public pool cant report a proper hashrate. Its not cgminer as I have a gekko compac connected and hashing just fine alongside my bitaxes.

Did you get this figured out? I’m having same issues.

@Catnip @RainBitcoins can look into this. yes current app store version isn’t the latest release.
we’ve had reports in the past of public-pool going down a lot on devices with low RAM, but this doesn’t sound like the case here.

@smolgrrr @RainBitcoins No nothing yet. However it works fine on public-pool.io and kano.is. So it’s not the miner. The fact that it works on public-pool.io shows it must be the app version on Umbrel. Hopefully they will update it soon.

Can you update this app please ?

I’m having the same issue. The Avalon 3 , constantly disconnects. I have 3 units, and they all behave the same.

IS there a different Stratum server we can use?

I think that it has to be something related to the public pool app… I have several and they work great! :slight_smile:

Also, if you want to control your Avalon Nano from the command line, I just made a tool for that… I have several around the house to help heat the bedrooms, and with this cli tool I am able to automate power changes through out the day, based on the production of my solar panels, and at night switch off the led for kids to sleep, all from cron jobs on my server and home assistant.

It was fun to build, check it out on github: GitHub - prcolaco/avalon-nano-cli: Makes commanding the Canaan Avalon Nano 3 Bitcoin little home miners fun

So far my Avalon Nanos are doing a great job at both heating and mining! Have fun fellow miners!

Public pool app on Umbrel works for you with Avalon Nano 3 ?

Hello,

Are you using the Public pool app on Umbrel and it works fine for you with the Avalon Nano 3 ?
If so, could you please let us know how do you use it successfuly ?

Thanks!

I set my username to btcaddress.minername

and it worked. Where I had issues with the solo online public pool without the .miner name

Guys, it seems that the last update fixed things and now I have my nano working uninterruptedly for 3 days!! :raised_hands: :tada:

15

Yeah, same here :clinking_glasses:

16

I’m having the same issue. Version 9c14003 of the Public Pool app. Has anyone isolated this issue and figured out a way around it?

17

For me it wasn’t working before the update to 9c14003, after the update it just works.

18

Interesting, OK. Well, I figured it out anyhow after looking at my logs in my Nano 3. Dead giveaway was:

2024-11-12 19:47:43 369 INFO Failed to getaddrinfo for umbrel.local:2018

I pointed my miner at my umbrel’s IP address instead of hostname (i.e. 192.168…) and it works perfectly now!

In the app store, click on updates.

It should prompt the update, if you don’t see it just go to the app store and click update
