![PowPeg App (peg-out)](/img/resources/powpeg/pegout.gif)

You may encounter the following errors when trying out the application:

## Trezor will not connect (browser pop-up blocked) {#trezor-connect-popups}

The PowPeg App uses Trezor Connect in a browser pop-up. Chrome and Brave can block that window. When the pop-up is blocked, Trezor may not connect and the PowPeg App can show a generic error.

**What to do:**

1. Connect your Trezor and open the PowPeg App in Chrome or Brave.
2. Click **Connect wallet** and choose **Trezor** so the browser tries to open Trezor Connect.
3. Look for a **pop-ups blocked** icon in the address bar. Click it.
4. Select **Always allow pop-ups and redirects from** the PowPeg App URL you are using:
   - Mainnet: `https://powpeg.rootstock.io`
   - Testnet: `https://powpeg.testnet.rootstock.io`
5. Click **Done**, reload the page, and try again.

Other Rootstock web apps that use Trezor Connect need the same setting for their own site URL.

If Trezor still does not connect, confirm **Perform Safety Checks** is set to **PROMPT** in Trezor Suite. See [Peg-in using Trezor](/resources/guides/powpeg-app/pegin/trezor/) or the [Forbidden key path FAQ](/resources/guides/powpeg-app/faqs/).

## BTC not visible after a peg-out (Trezor and Electrum)

The peg-out can succeed on chain while your balance still shows zero in Trezor Suite or Electrum.

**Cause:** Trezor Suite does not support the custom derivation path for peg-out Bitcoin addresses. Electrum is required to view those funds. A common mistake is to enter a BIP39 passphrase in Electrum when you do not use one on Trezor. That opens a different wallet than the one used for the peg-out.

**What to do:**

1. Confirm the Bitcoin transaction on a block explorer using the destination address from the [PowPeg status page](https://powpeg.rootstock.io/).
2. Follow [Viewing a derived bitcoin address](/resources/guides/powpeg-app/pegout/deriving-electrum/#import-key-in-electrum-using-hardware-wallets) with path `m/44'/137'/0'` on Mainnet.
3. Leave the Electrum passphrase fields empty if you do not use a BIP39 passphrase on Trezor. See [Trezor passphrase in Electrum](/resources/guides/powpeg-app/pegout/deriving-electrum#trezor-passphrase-in-electrum).
