I'm about ready to give up, for the life of me I can't figure out how to get my new L3+ to start mining. I think I've got everything entered correctly - I'm using the same setting I used years back mining LTC successfully with a few Moonlanders. I've tried other pools (litecoinpool, Prohashing, Antpool), turning off all the antivirus on my router (TP-Link Deco mesh router), and even plugging the ethernet cable directly into the modem and bypassing the router completely. Unfortunately whatever I try I get the error: local0.notice cgminer: Pool connection FAILED. Check INTERNET, POOL URL or WORKER

Can anyone help? Thanks guys!

Maybe check the pool website for the current settings port....etc may have changed.
Maybe provide the settings you are using so we can see if there is something incorrect.

Good idea! Let me see if I can attach some screenshots for my litecoinpool settings at least and the Kernal Log.

The pool you are trying to mine too does not exist.  At least not that i can find anywhere....

Try any of these :

https://miningpoolstats.stream/litecoin

It's #7 on the list on that link you posted. I also tried #5 and #13.

Ack missed it...tried going to their web url resolved to litecoin.org....so yeah pool is there...address matches..but isnt connecting pe your log pic..it states pool connection failed.  

Can you login to the pool on the webpage?  

Your config looks correct as long as the user id matches (case sensative).  Can you ping the miner on the local network?  did you check the dns settings (8.8.8.8 is a solid dns from google).  

The error is POOL connection failed.  Check Internet, Pool URL, or Worker. 

Pool Url looks correct.
Worker looks correct (double check you can log in via web)
So internet...check all your settings and try pinging or ssh into the asic from another computer.  Double check Netmasks and DNS settings. 

Yeah, I can login to the pool webpages fine, just no hashing is going on when I do. I can also connect to the miner on my network without issue and change settings, reboot, etc. It's just for some reason the miner can't connect to any of the pools.

Did you see Bitmain has new firmware for it from 2019...

https://service.bitmain.com/support/download?product=AntMiner%20L3%2B

There are also alternative optimzations from Hive Os and others for this miner.  I am looking to see if Bitmain locks your SSH ability with that firmware.  So read up before doing it...but may be as simple as old firmware. 

Sounds like a default gateway, subnet or DNS problem then.  Make sure all those network settings are correct.

I should have mentioned this earlier, but the guy I bought it from had first flashed it to latest VNISH firmware.

What am I looking for with those settings? Sorry, I'm not very experienced with routers, everything is just set to the defaults (and is working fine for everything else).

okay to be clear


pretend your miner is at

192.168.0.153 on your network


go to net work and look to see

if it says.

address.       192.168.0.153
net mask.     255.255.255.0
gateway.       192.168.0.1
DNS servers. 1.1.1.1   note 8.8.8.8 works. and if you are on a router with 192.168.0.1 that works.



show us these settings.

here is a gui from a braiins s9

Under Settings tab on the L3+

Netmask = is usually 255.255.255.0 (but can be different)
Gateway = your routers ip usually 192.168.0.1 or similar 1.1
DNS = 8.8.8.8.

On windows pull up a termianl screen and type IPCONFIG
look for Ethernet #

And should show you

IP address (which will be the address of the windows machine you are on)
Subnetmask (this is the netmask and you should set the netmask on L3+ to what the pc shows)
Default Gateway (this is the gateway to the router and you should set the gateway on the L3+ to what the pc shows)
Set DNS to 8.8.8.8

Save it and reboot the L3+...

better here is a screen shot of proper l3+

Thanks everyone, here's what I got:

https://ibb.co/phnvc6C

You have no gateway and no dns specified (fields are empty)

Can you run the IPCONFIG?  and share the ip and gateway so we can double check you settings.


Then copy the gateway from ipconfig to l3+.
Set dns to 8.8.8.8

Also share the netmask...you show 255.255.255.0. but i wonder if this should be 255.255.0.0 based on your ip....ipconfig from a machine on the network will answer this...just copy what ipconfig shows to the miners netmask.

yeah he has that weird ip

192.168.68.132

so

192.168.68.132
255.255.255.0
192.168.68.1
8.8.8.8

may work

At op  if you go to a pc and put in 192.168.68.1 does it try to connect to your router?

I think modem>>> router>>>> switch>>>>pc and miner  for a

grand total of 4 boxes may be basic trouble shoot method.

I am not sure how you got an ip of 192.168.68.132

I'm not sure why my router picks from that range of IPs, but that's the default. It's definitely the right IP though.

I'm on a Mac, not sure how to find the gateway, any ideas?

On mac....system preferences >>> network

Then click advanced (lower right corner of window) then click on tab tcp/ip

Will show subnet mask and router (gateway)

You guys, that worked! I really can't thank you all enough, I'm so excited to get mining again!

sweet!!

the weird router number was making the trouble

I'm so irrationally excited to be losing money mining LTC again! Thanks again to everyone that helped today, after four years of dreaming of one I finally have my own L3+ ;D

As long as you are happy...we are happy for you :)

Thanks miner29, I can't get the smile off my face. I had almost completely given up before you replied to the thread.

Never give up....just sometimes takes a bigger hammer :)
