Timing out when adding data to IPFS node

[Jeff_Zhu]

today, in my project, ipfs.add() is not work. when i upload file, it return timed out…

this is my code:
//Declare IPFS
const ipfsClient = require(‘ipfs-http-client’)
const ipfs = ipfsClient({ host: ‘ipfs.infura.io’, port: 5001, protocol: ‘https’ })

  //Upload video
  uploadVideo = title => {
    console.log("submit to ipfs")

    ipfs.add(this.state.buffer, (error, result) => {
      console.log("IPFS result: ", result)
      if(error){
        console.log("error: ", error)
        return
      }
    })
  }

Many thanks.
