Why does contract launch on ropsten but not BSC testnet with remix?

Unable to launch Storage.sol on BSC Testnet but it works on Ropsten and I have no idea why. Using Brave Browser and Metamask however switching browsers and wallets doesn't seem to help. Have successfully launched on Polygon's Mumbai network so it has to be BSC Testnet, but I can see other people posting new contracts on the test explorer :/. Any ideas on how to resolve this?

        number = num;
    }

    function retrieve() public view returns (uint256){
        return number;

Solution

  • You may have set BSC Testnet on Metamask like this:

    New RPC URL: https://data-seed-prebsc-1-s1.binance.org:8545/

    Chain id: 97

    But change into this:

    New RPC URL: https://data-seed-prebsc-2-s3.binance.org:8545/

    Chain id: 97

    If still doesn't work, also change Chain ID into 0x61
