minting error in goerli network

[kwanlae]

Clicking "Mint Free Tokens" button in goerli network, I have received below error message,

vendors.app.js:70740 Uncaught (in promise) Error: Provider not set or invalid
    at Object.InvalidProvider (vendors.app.js:70740)
    at RequestManager.push../node_modules/web3-core-requestmanager/src/index.js.RequestManager.send (vendors.app.js:72279)

    at Generator.prototype.<computed> [as next] (commons.app.js:4497)
    at asyncGeneratorStep (commons.app.js:31)

It seems to be a problem about goerli infura.io. Could you check this?
Thanks.
