[fixed] httpd and nginx graphs broken

Hello
I have just noticed that one of our Vesta VPS (OVH/CentOS7/CloudFlare) stopped showing httpd and nginx graphs (another graphs works ok) yesterday.
I was looking for solution, but no luck. Any hints, how can I debug/fix that?
Thank you in advance,
Krzysztof

Ok, one hour later after some debugging...
Problem: CloudFlare pointed domain to different IP, so /usr/local/vesta/bin/v-update-sys-rrd-nginx could not obtain data from localhost at port 8081 as it was blocked
Fix: /etc/hosts - remove # from line:
127.0.0.1 localhost

2 days later the problem is back. But now only httpd graphs are broken. Any advice where shall I start the investigation now?

Ok, problem found:
/etc/httpd/conf.d/status.conf
Listen 127.0.0.1:8081
<Location /server-status>
SetHandler server-status
Order deny,allow
Deny from all
Allow from *allowed IPs goes here* 127.0.0.1 <-- you can not remove localhost IP from this line, adding it back solved the problem
</Location>
service httpd restart and voila :)
