Are you sure your approvals are correct?

                IERC20Modified(currentCoin).approve(address(this), _amountTIndexes[i]);
                IERC20Modified(currentCoin).transferFrom(msg.sender, address(this), _amountTIndexes[i]);

the caller should be allowing your contract to spend the tokens. here on the first line your contract is approving itself.
then your contract needs to approve the pool's contract for spending each of the token you'll deposit before it can deposit there.

My guess is that you need

IERC20Modified(currentCoin).approve(curveFiPool, _amountTIndexes[i]);

@benber86 Yes, I tested the Deposit of ERC-20 Tokens from the Wallet to my Operator S.C. (That Uses address(this)) in an Isolated way and it worked:

    /// @param _amountTIndexes: List of Amounts of Different Coins to Deposit. Ex: [2 DAI, 4 USDC, 3 USDT].
    function depositLiquidityInOperator(address curveFiPool, uint256[3] memory _amountTIndexes) external {
        for (uint256 i = 0; i < 3; i++) {
            if (_amountTIndexes[i] > 0) {
                address currentCoin = ICurveFiPool(curveFiPool).coins(i);
                IERC20Modified(currentCoin).approve(address(this), _amountTIndexes[i]);
                IERC20Modified(currentCoin).transferFrom(msg.sender, address(this), _amountTIndexes[i]);
            }
        }
    }

My guess is that you need

IERC20Modified(currentCoin).approve(curveFiPool, _amountTIndexes[i]);

Thanks, I will try that...

My guess is that you need

IERC20Modified(currentCoin).approve(curveFiPool, _amountTIndexes[i]);

IT WORKED YOU ARE A DAMN GENIUS I HAVE BEEN STRUGGLING WITH THAT SH*T FOR DAYS THANK YOU VERY MUCH!!! A STRONG HUG!!!
