在 Solana devnet Metaplex v1.2.0 candy-machine-ui 上铸造 NFT 时收到错误

Question

Running metaplex version to 1.2.0, and using 3 basic NFT's (stored on Arweave). When minting on devnet I receive a Timeout Error.

I have tried minting on Metaplex's candy-machine-ui and a separate ui that uses javascript. Both receive same error. Timeout Error caught Error: Timed out awaiting confirmation on transaction at sendSignedTransaction

Tried downgrading metaplex to v1.1.1; still, receive Timeout Error.

Tried the following RPC Hosts, still received Timeout Error: -https://explorer-api.devnet.solana.com -https://metaplex.devnet.rpcpool.com/

The metaplex.devnet.rpcpool (came stock with candy-machine-ui) actually gives me CORS errors, but regardless still no mint.

Network has always been set to devnet

Tried the follwoing Candy Machine IDs: 64EFEgBcLZHhdb3Tr6BzCRKX23ktS2Ltk42RC3z9CPLP & 492Mhv2Kx6Mp91D1xyrXgDA9ZKeeXSRg2rWuN6LA2Qg6

Tried these config.json :

Thanks I take a look to both CandyMachineIds that you provided and was able to mint without any issue using the last version of candy-machine-ui with this the Candy Machine 64EFEgBcLZHhdb3Tr6BzCRKX23ktS2Ltk42RC3z9CPLP . Your second Candy Machine with ID 492Mhv2Kx6Mp91D1xyrXgDA9ZKeeXSRg2rWuN6LA2Qg6 has the goLiveDate setted at Sunday, December 25, 2022 12:00:00 AM so anyone will be able to mint that.

What did I do to be able to mint?

1. I git clone the latest version of candy-machine-ui into my laptop using git clone https://github.com/metaplex-foundation/metaplex.git
2. I move away the candy-machine-ui folder located at metaplex/js/packages/ to my Desktop.
3. I open a terminal on the candy-machine-ui folder that I moved to my Desktop.
4. I run yarn inside this candy-machine-ui folder.
5. I create a .env file inside candy-machine-ui folder with the following content

REACT_APP_CANDY_MACHINE_ID=64EFEgBcLZHhdb3Tr6BzCRKX23ktS2Ltk42RC3z9CPLP

REACT_APP_SOLANA_NETWORK=devnet
REACT_APP_SOLANA_RPC_HOST=https://metaplex.devnet.rpcpool.com/
SKIP_PREFLIGHT_CHECK=true

6. I ran yarn start and waited till the localhost appear.
7. I make sure to have 0.2 SOL in the wallet that I used to mint (0.1 mint price + fees)
8. I clicked mint button and minted successfully without any other issue.

Hope this can hep you solve, any issue add a comment to this answer to keep me updated

EDIT: I used Opera browser with phantom wallet to mint from the UI

That is caused beacuse of the slow RPC you're using.

Follow one of these solutions:-

• Use a custom RPC from Quicknode

• For a free and fast one, use https://devnet.genesysgo.net/ (Devnet)

  https://ssc-dao.genesysgo.net/ (Mainnet)
