Tendermint: no blocks generated

[bgrieder]

I'm running:

• Which Parity version?: v1.9.4-beta-6f21a32-20180228/x86_64-macos/rustc1.24.0
• Which operating system?: MacOS
• How installed?: via installer binaries
• Are you fully synchronized?: yes
• Which network are you connected to?: custom
• Did you try to restart the node?: yes

This setup of 3 validator nodes work fine with Authority Round (blocks are generated) but does not work with Tendermint (validators see each other but no blocks are generated). The general guidelines of https://wiki.parity.io/Demo-PoA-tutorial.html have been followed.

From the working set-up for Aura, the engine entry of genesis.json was replaced:

I was able to reproduce the issue here with the panic at the end:

Thread 'IO Worker #1' panicked at 'Invalid header.: RlpIsTooShort'

Trying to dig deeper.

@bgrieder Hi, I am trying to do a similar setup (using docker containers ref). Even for me, the blocks are not being mined. Have you found the reason? My tendermint-config file looks like :

{
  "name": "parity-tendermint",
  "engine": {
    "tendermint": {
      "params": {
        "validators": {

          ]
        }
      }
    }
  },

  },

    },
    "difficulty": "0x20000",

  },
  "accounts": {
    ...
  }
}

I am getting this log in the still running authority/validator:

Also, one container failed and stopped due to this error:

What is wrong?

[ordian]

@roynalnaruto the panic was fixed in #8367 (not yet in stable), however the parity's tendermint engine is still not ready for production use.

The error you're getting (Engine(NotAuthorized(...))) is different though, make sure you have engine_signer in your node config (see demo poa tutorial).

[roynalnaruto]

@ordian I had used --engine-signer while launching the docker container. What is the id in the brackets of the above error 66ae460c87cca597b3b8fee210b07cad7b9a448d? Because, that is not the public address of any of the 4 validators that I am using. Below is the docker-compose.yml I am using:

I have mentioned only 2 of the authorities, rest of the yaml file follows the same pattern

And this is the authority.toml

I bumped into this. Anyone solved it??
