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
