Whitelist Domain on Dashboard

I tried to whitelist my domain on the dashboard but still got an error message in my webapp.

OpenLogin - RPC Error: could not validate redirect, please whitelist your domain: https://gymwallet.co for provided clientId ... at https://dashboard.web3auth.io.
    Also, this project is on mainnet network. Please ensure the the used Client ID belongs to this network. 



my configuration looks like this:

const web3auth = new Web3Auth({
  web3AuthNetwork: 'testnet',
  clientId: clientId,
  chainConfig: {
    chainNamespace: CHAIN_NAMESPACES.EIP155,
    chainId: `0x${network.toString(16)}`,
    rpcTarget: url,
  uiConfig: {
    appLogo: '/community/images/gym-wallet-white.svg',
    defaultLanguage: 'en',
    theme: 'dark',
    loginMethodsOrder: [
  storageKey: 'local',
  authMode: 'DAPP',

I'm using infura RPC and want to try it out on testnet first.
Like this with localhost, all works fine, but not on my domain.
Help would be appreciated.

Even I am facing this issue, do I really have to switch to mainnet to solve this?

Thanks @sebastian-baier @Ni3l55

That worked, testnet isnt working for some reason on urls other than localhost.

Also web3AuthNetwork: "mainnet" should be configured to make it work.

Now it is accessible from the whitelisted URLs
