Finicity API Issue - php

Question

We are using the finicity API to get statements and transaction. We have followed below steps, but we are getting "aggregationStatusCode:185" while fetching the customer accounts [ https://api.finicity.com/aggregation/v1/customers/['customer_id']/accounts ].
To get the custommer account I am using https://api.finicity.com/aggregation/v1/customers/['customer_id']/accounts.
Then we are fetching statements for account using "https://api.finicity.com/aggregation/v1/customers/['customer_id']/accounts/['account_id']/statement?index=1; this loops for 6 times. We need 6 months statement for each account.
Then, we are fetching transaction for account using "https://api.finicity.com/aggregation/v1/customers/['customer_id']/accounts/['account_id']/transactions?fromDate=".$from."&toDate=".strtotime(date('Y-m-d'))."&limit=".$transactionLimit."&includePending=true";
We are facing the below two issues.
1. Getting timeout error, when selecting more than 2 accounts.
2. Getting "aggregationStatusCode:185" for some live accounts.
Below are the code for reference.
function get_statements(){
$FinicityAppToken=$_POST['FinicityAppToken'];
$customerId=$_POST['customerId'];
$leadId=$_POST['leadId'];
$finicityConnectUrl=$_POST['finicityConnectUrl'];
$NoOFStatements = 6;
$transactionLimit = 100;
$transactionsMonth = 1;
$url="https://api.finicity.com/aggregation/v1/customers/".$customerId."/accounts";
$response=callAPI('POST', $url,false,$FinicityAppToken);
$response = json_decode($response);
$allstatements=array();
if($response){
if(isset($response->accounts)){
$accounts = array();
$array = array();
foreach($response->accounts as $account){
if ($account->aggregationStatusCode == 0 && $account->aggregationSuccessDate != '' && $account->aggregationAttemptDate != '') {
for($i=1;$i<=$NoOFStatements;$i++) {
$url="https://api.finicity.com/aggregation/v1/customers/".$customerId."/accounts/".$account->id."/statement?index=".$i;
$stateresponse=callAPI('GET', $url,false,$FinicityAppToken);

$temp['statement'] = base64_encode($stateresponse);
$statements[]=$temp;
}
$act = array();
$month = date('m') - $transactionsMonth;
$from = strtotime(date('Y').'-'.$month.'-1');
$url="https://api.finicity.com/aggregation/v1/customers/".$customerId."/accounts/".$account->id."/transactions?fromDate=".$from."&toDate=".strtotime(date('Y-m-d'))."&limit=".$transactionLimit."&includePending=true";
$data['url'] = $url;
$transactions = json_decode(callAPI('GET', $url,false,$FinicityAppToken));
$act['account']['accountNumber'] = $account->number;
unset($account->number);
$act['account']['currencySymbol'] = $account->currency;
unset($account->currency);
if(empty((array) $account->detail)) {
$account->detail = (object) transactionsDetailsEmpty();
}
$act['account'] = json_decode(json_encode($account), true);
if(isset($transactions->transactions)) {
$act['transactions'] = $transactions->transactions;
} else {
$act['transactions'] = array();
}
// echo "step";
$accounts[] = $act;
} else {

die();

$j++;
