Getting error 403 from cloudflare

Hey all,

I am sometimes getting 403 error from cloudflare. If I wait for a while then it starts working again, but then it stops working again.

<html>
<head><title>403 Forbidden</title></head>
<body>
<center><h1>403 Forbidden</h1></center>
<hr><center>cloudflare</center>
</body>
</html>

headers:

content-length: 553
content-type: text/html

server: nginx

The first thing I did was check my WAF firewall logs, but it seems that there are no records about blocking my IP. The funny thing is that if I use VPN or incognito mode, the error disappears.

Any idea what could be happening?
