„Betrieb auf dem Gerät verweigert“

This error message would indicate that you aren’t confirming the transaction manually, using the physical Ledger device.

When you attempt these swaps, are you getting any sort of notification message on your Ledger device, asking for you to confirm the transaction?

Also, when you’re trying this transaction, do you have the ETH application **open** on your physical Ledger device? Importantly, you’ll need to **close** any/all 3rd party wallets other than Ledger Live (if you’re swapping from within Ledger Live).

If you’re using a 3rd party wallet, such as a MetaMask account to connect to Curve/ParaSwap/1inch, you’ll need to make sure Ledger Live is **closed** (as Ledger Live functions as a crypto wallet UI as well).

Ah I got it to work while connecting my ledger to [https://app.1inch.io/](https://app.1inch.io/)

I suppose ledger live is not yet really compatible with certain apps.

​

thanx for the responses guys / fixed

I had a similar problem with a simple swap from link to matic. The problem was 1inch. I used uniswap and problem was fixed
