The API endpoint is decribed here: https://dev.moip.com.br/v2.0/reference#listar-todas-preferencias-de-notificacao
It had been worked for last months, but today the Moip API server responds:

<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
<html><head>
<title>502 Proxy Error</title>
</head><body>
<h1>Proxy Error</h1>
<p>The proxy server received an invalid
response from an upstream server.<br />
The proxy server could not handle the request <em><a href="/v2/preferences/notifications">GET&nbsp;/v2/preferences/notifications</a></em>.<p>
Reason: <strong>Error reading from remote server</strong></p></p>
</body></html>

I have got a response from the Moip support:

We were facing a small issue today, although the problem was solved, would you mind trying to access the API again?

I handle this exception since the 1.2.0 Moip extension version:
