Chopstick fail to connect to Electrs when faucet is enabled

[loic86]

Hi,
I'm trying to run nigiri and I managed to get all the containers running.

• The blockchain is initialized with 101 blocks.
• The electrs works if I do: curl http://localhost:30000/blocks/tip/height I get 101.
• The chopstics fail to start and I get these logs:
  chopsticks | time="2023-02-10T14:44:23Z" level=info msg="Starting server with configuration:" chain=bitcoin electrs_url="http://electrs:30000" faucet_enabled=true listen_url="0.0.0.0:3000" logger_enabled=true mining_enabled=true rpc_server_url="http://admin1:123@bitcoin:18443" tls_enabled=false
  chopsticks | time="2023-02-10T14:44:23Z" level=fatal msg="rescan blockchain" error="could not rescan: Method rescanblockchain failed with error: Wallet is currently rescanning. Abort existing rescan or wait."

Then, of course also esplora is not working

Instead all the liquid containers run correctly.

This is the docker ps:

Thanks in advance for your time!

Interesting! let me try to replicate: Are you on Mac (Intel or Apple chip?) or Linux?

[loic86]

I'm on arch linux

It seems bitcoin core has trouble syncing: can you try nigiri stop --delete && nigiri start again?

Ok I did restart nigiri as you suggested, at the very beginning of chopsticks logs I get:
chopsticks | time="2023-02-10T15:11:20Z" level=info msg="Starting server with configuration:" chain=bitcoin electrs_url="http://electrs:30000" faucet_enabled=true listen_url="0.0.0.0:3000" logger_enabled=true mining_enabled=true rpc_server_url="http://admin1:123@bitcoin:18443" tls_enabled=false

chopsticks | time="2023-02-10T15:11:48Z" level=fatal msg="rescan blockchain" error="could not rescan: Timeout reading data from server"

chopsticks | time="2023-02-10T15:11:55Z" level=fatal msg="rescan blockchain" error="could not rescan: Method rescanblockchain failed with error: Wallet is currently rescanning. Abort existing rescan or wait."

So, first it gets: chopsticks | time="2023-02-10T15:11:38Z" level=warning msg="Faucet not funded, check the error" error="Timeout reading data from server" status=500 and then start the loops

Does just waiting ie. 5 seconds help? I can't replicate the issue on Mac Apple chip

[loic86]

I'm trying to manually stop and only start the chopsticks container with: cd ~/.nigiri && docker-compose run chopsticks and I still get the same:
INFO[0000] Starting server with configuration: chain=bitcoin electrs_url="http://electrs:30000" faucet_enabled=true listen_url="0.0.0.0:3000" logger_enabled=true mining_enabled=true rpc_server_url="http://admin1:123@bitcoin:18443" tls_enabled=false
FATA[0010] rescan blockchain error="could not rescan: Timeout reading data from server"

but if I remove the --use-faucet flag I get chopsticks running correctly (on the left) and then I can also run esplora (on the right)

so the issue arise when the faucet is enabled.

oh thank you so much for the debug! Will dive into it over next days

Can you try this latest release and see if it fixes on your side? https://github.com/vulpemventures/nigiri/releases/tag/v0.4.14

Thank you! I tried but I get the same error on esplora UI and workaround to make chopstick work by commenting out:

• --use-faucet
  If I try to run the chopstick with: docker compose up chopsticks I get:
