  Hey hey! I'm not sure I understand the question as you mention intermittent 400 errors, DNS cache, and 403 errors. It's possible these are not related issues at all, so it would be best to pick one and get that resolved. The 403 will leave something in the server's Apache logs at /etc/apache2/logs/error_log. Can you check that file while refreshing the page the see if you find any useful details?

  right.. the 403 error was because I was enabling debug logging for a domain, but to do that you need to use nginx-debug service (

  I would say it's time to make a ticket on this so we can take a look directly.

  Hello, after very long ticket i have some useful info. first of all it must be said that it was a big problem not having the way to reproduce the problem. another difficulty was the lack of logs because apparently this 400 error does not come out in the warn log level. moreover I was not able to put the "debug" log level on nginx, not even through cpanel support which inform me about an internal case
