Unable to Deploy Contracts on Custom Network

[praddoskanna]

I am trying to deploy an sample erc20 contract in ozonechain , but remix returns me this error .

Gas estimation errored with the following message (see below). The transaction execution will likely fail. Do you want to force sending?
Returned error: Internal error
[object Object]

creation of TestToken pending...
creation of TestToken errored: Error occurred: Internal error.

Internal error

You may want to cautiously increase the gas limit if the transaction went out of gas.

Network :

Name - "Ozone Chain Mainnet",
Chain - "OZONE",
RPC - "https://node1.ozonechain.io"
ChainId - 4000,
Explorer - "https://ozonescan.io"

Contract Code :
// SPDX-License-Identifier: MIT
// Compatible with OpenZeppelin Contracts ^5.0.0
pragma solidity ^0.8.20;

import "@openzeppelin/contracts/token/ERC20/ERC20.sol";

contract TestToken is ERC20 {
constructor() ERC20("TestToken", "TST") {
_mint(msg.sender, 1000 * 10 ** decimals());
}
}

I can reproduce it. It seems an error with RPC

I see same RPC address is given on chainlist too https://chainlist.org/chain/4000 but in browser console, it shows this:

which seems a RPC call related issue

Hi @Aniket-Engg

I'm able to deploy contract via Hardhat and custom network configuration. But get this error while using Remix. Can you suggest me an fix or alternative to this issue.

Hi @Aniket-Engg is there any updates on this issue?
