Every midnight (+2 to UTC) i received following errors?
Error from VRM: <html>
<head><title>429 Too Many Requests</title></head>
<body>
<center><h1>429 Too Many Requests</h1></center>
<hr><center>nginx</center>
</body>
</html>
1. What are current limits on nginx?
2. Why only once a day, at midnight?
