# How to disconnect from Algorand Mobile Wallet/ WalletConnect using reach?

Hello guys,
So I’m working on reach and algorand mobile wallet / WalletConnect to add the wallet to my dapp. I connect it successfully but I am unable to find a way to disconnect it. In the official docs of WalletConnect there is a `killSession()` function. I was wondering, how to `killSession()` using…

## Algoexplorer: Access to fetch at 'https://node.testnet.algoexplorerapi.io/v2/accounts/AccountNumber' has been blocked, Error 403

Thanks for the reply,
I was actually looking for the data related to that account, which I repeat was working perfectly fine on the previous (soon to be depreciated) link.

## Share WalletConnect session between client and server?

Thanks for your reply!
Yes I’ve tried that multiple times but it seems to work randomly. Without any errors logged it just displays a message of dapp not responding and after sometimes starts working perfectly fine.

## Is WalletConnect service down?

Hey, WalletConnect has stopped working for my website frontend.
I scan the QR from mobile app but nothing happens, no error logs. Just the mobile app says that your dapp isn’t responding. I tried connecting my app to this demo link by algorand [https://algorand.github.io/walletconnect-example-dapp…](https://algorand.github.io/walletconnect-example-dapp/)

Hey everyone,
So I’ve changed the testnet API link for algoexplorer as per their announcement that they’re depreciating the (https://api.testnet.algoexplorer.io/v2) by February, so I changed my api testnet link to 'https://node.testnet.algoexplorerapi.io/v2.

## TransactionPool.Remember: transactionGroup: [0] had zero Group but was submitted in a group of 2

Yeah, I had the same issue in which I was not assigning the group IDs correctly.

## Invalid Input: Group transaction does not need to be signed by Wallet user

Thank you so much,
I was assigning groupID in the wrong way.

### Code Example

```javascript
let requestObj= [];

txnsToSign.forEach(txn => requestObj.push(txn));
txnsNotToSign.forEach(txn => requestObj.push(txn));

requestParams = [requestObj];
const request = formatJsonRpcRequest('algo_signTxn', requestParams);
const result = await this.walletConnect.sendCustomRequest(request);
```

## Invalid Input: Unable to parse transaction

Hello, I need some help regarding solving this error.
I have two transactions, one is signed by logicSign and other is supposed to be signed using WalletConnect.

```javascript
const txnsToSign = txsToSign.map(txn => {
    const encodedTxn = Buffer.from(algosdk.encodeUnsignedTransaction(txn)).toString('base64');
    // further processing...
});
```

## Validation failed for transaction because of invalid properties [group]

Hello, I am working on AlgoSignerWallet and previously my sign function for grouped transactions was working fine but now it is throwing this error.
Validation failed for transaction because of invalid properties [group].

## TransactionPool.Remember: transactionGroup: [0] had zero Group but was submitted in a group of 2

Hi, I am trying to post a group transaction but receive this error. I am using WalletConnect to connect the wallet and to sign the transactions.

```javascript
txObj = new algosdk.Transaction(txs[0].getTx(TX_FORMAT.SDK));
```
