Localnet does not produce blocks

[soywod]

Describe the bug

I try to create a subnet following this documentation: https://docs.bittensor.com/subnets/create-a-subnet.

Running ./scripts/localnet.sh works, but then shows indefinitely the same log:

$ ./scripts/localnet.sh

When I run:

$ btcli wallet faucet --wallet.name owner --subtensor.chain_endpoint ws://127.0.0.1:9946
Run Faucet ?
 coldkey:    5F93HA9yz1TnHqAnLV4BChgYY8TjSEmqq24BBQcFAYTQtMQk
 network:    local [y/n]: y

It just hangs, no logs from both sides.

To Reproduce

Just follow documentation on subnet creation: https://docs.bittensor.com/subnets/create-a-subnet

Fails on wallet faucet command due to freeze.

Expected behavior

I expect the wallet faucet command to output:

>> Balance: τ0.000000000 ➡ τ100.000000000

Environment

NixOS 24.05, bittensor cli v7.2.0, subtensor branch development (ebb72e)

Thanks for reaching out @soywod . What branch subtensor branch are you building off ?

[soywod]

I tried main, then v1.1.2, v1.1.1-pre-release and finally development.

I initiated the discussion on Discord (the forum section), I received some help. Somehow running the localnet script from a docker (debian) works, so it looks like an issue with the network (related to NixOS?). Now I have a ConnectionResetError: [Errno 104] Connection reset by peer when I attempt to wallet faucet.

[soywod]

I finally found the solution: mDNS was disabled on my OS and I needed to enable it for nodes to be discovered. I will propose a PR to improve the doc.

[distributedstatemachine]

Sounds good. can you please submit the PR and link it to this issue so we can close it.

[soywod]

Yes, I was planning to do so. Thank you!

[distributedstatemachine]

@soywod still waiting on that PR sir!

I do not forget, I am just a bit short in time these days.
