Rinkeby contracts deployment Error: Timeout - timeout

Question

I was trying to follow this tutorial:
https://docs.opensea.io/docs/1-structuring-your-smart-contract
And even found this extremely helpful YouTube video to guide me:
https://www.youtube.com/watch?v=lbXcvRx0o3Y&ab_channel=DanViau
But I've encountered a problem after installing and setting up everything I needed. The problem occured when I tried to deploy the contracts using this bash command:
truffle deploy --network rinkeby
The error message I got is:
Error: There was a timeout while attempting to connect to the network.
Check to see that your provider is valid.
If you have a slow internet connection, try configuring a longer timeout in your Truffle config. Use the networks[networkName].networkCheckTimeout property to do this.
at Timeout._onTimeout (C:\Users\alonb\.nvm\versions\node\v12.22.5\bin\node_modules\truffle\build\webpack:\packages\provider\index.js:56:1)
at listOnTimeout (internal/timers.js:554:17)
at processTimers (internal/timers.js:497:7)
It's not caused by slow internet connection - I know that because I have tried executing this command on 3 different WiFi connections, one at 200 Mb/s rate.
I have tried to change the truffle-config.js file and add a longer timeout threshold (like suggested here), but the only thing that changed was that the error message took much longer to appear.
Technical info - I'm using Git Bash, npm version 6.14.14, nvm version 0.38.0, node version 12.22.5.
Any suggestions? I'm lost.

Answer 1

I also ran into this error when following the same tutorial.
I use Alchemy (not Infura), and the issue was my API_KEY.
In other tutorials I've followed, the scripts require the full alchemy API Key (ex. "https://eth-rinkeby.alchemyapi.io/v2/<random-key>").
So, when I was following this tutorial, that is what I supplied. And, I ran into the error you reported.
But when I reviewed the truffle.js script provided by the tutorial authors, I found this:
const rinkebyNodeUrl = isInfura
? "https://rinkeby.infura.io/v3/" + NODE_API_KEY
: "https://eth-rinkeby.alchemyapi.io/v2/" + NODE_API_KEY;
Thus, the script was producing:
rinkebyNodeUrl = https://eth-rinkeby.alchemyapi.io/v2/https://eth-rinkeby.alchemyapi.io/v2/<**random-key**>
...which is clearly wrong.
Thus, ensuring I set my API_KEY environment variable only to random-key and not https://eth-rinkeby.alchemyapi.io/v2/https://eth-rinkeby.alchemyapi.io/v2/<random-key>, my contract deployed successfully.
Also, make sure you have enough ETH in your wallet on the Rinkeby network. Faucets always seem to work for a little while then stop working, so do some Google searches to find one that is currently functional.

Answer 2

The solution is incredibly easy -
Instead of using just the relevant part of the Alchemy key:
40Oo3XScVabXXXX8sePUEp9tb90gXXXX
I used the whole URL:
https://eth-rinkeby.alchemyapi.io/v2/40Oo3XScVabXXXX8sePUEp9tb90gXXXX

Answer 3

I had the same experience but when using hardhat not truffle.My internet connection was ok,try switching from Git bash to terminal(CMD).Use a completely new terminal avoid Gitbash and powershell.

Answer 4

Remove the function wrapper from provider inside the network configuration.
ropsten_infura: {
provider: new HDWalletProvider({
mnemonic: {
phrase: mnemonic
},
providerOrUrl: `https://ropsten.infura.io/v3/${project_id}`,
addressIndex
}),
network_id: 3
}

Answer 5

The rinkbery network has been decommissioned. Use Goerli or Sepolia network. Update your truffle config add a section for goerli in networks. E.g
goerli: {
provider: () =>
new HDWalletProvider(
mnemonic,
`https://goerli.infura.io/v3/${INFURAKEY}`
),
network_id: 5, // goerli's id
gas: 4500000, //
gasPrice: 10000000000,
}
The run the command
truffle deploy --network goerli
