Parachain nodes are not peering with default config

[brunopgalvao]

Using the default config with an additional parachain node, the relay-chain node and the parachain nodes are up and running but the parachain nodes are not peering. If I add the --force-authoring flag to the parachain nodes, the parachain starts creating blocks.

[brunopgalvao]

Is --force-authoring required, according to these docs it is:

• https://docs.substrate.io/tutorials/v3/cumulus/connect-parachain/#start-the-collator-node
• https://github.com/paritytech/cumulus#launch-the-parachain

And according to these it is not:

• --force-authoring flag handling in parachain node config #146
• Don't require --force-authoring any more. (#1) #143

If anyone can shed some light on this that would be great.

I am really experiencing this same issue.

polkadot-launch itself will add the flag --force-authoring when we are running one node alone for the parachain. See source here

A pair of things to check here then:

• Nodes are connected. We can run as many nodes as we want but if they are not properly connected, they will not produce.
• Check the paraId in the state of our para is matching the paraId where the wasm and state of the para has been registered on the relay chain. As mention here

If the configuration doesn't deviates much from a default config these should be one of the few checks to make for the parachain working as expected. For more custom chain specs and set ups the possible points of failure may vary

For parachain node peering to work for me, I had to replace the id field in the config.json:

"id": "200",

with the chain key and value of the parachain I am launching like this:

"chain": "statemine-dev",

then my parachain nodes peer, otherwise they do not.

Here is my config for reference:

Alright... Thanks so much, will try this out and give you feedback.

Closing this as it has resolved the stated issue. @dharjeezy if you are still having issues with running yours I would recommend opening a small replicable concise question on substrate.stackexchange.com as polkadot-launch does seem to be peering parachain nodes fine.
