Server errors + missing files

[Mantu2]

Hi,

I'm facing some issues with my server. My website is on a shared server and I'm just a admin for my site (Wordpress). I've asked the host provider help, but they are not too keen to their job. So, here is few things I would like to have help. I am not sure are they related to each others or not.

Firstly, my site over loads quite often. I can see that CPU usage causes faults as well Input/Output Usage. I do know that my Wordpress backend is a bit heavy, but the problems comes in waves - mostly things works fine until server overloads and my site gives 500-error. On those times I just need to wait a while and I'm ready to continue working.

Secondly, only thing what I can see from my error log is that there is basically only one error which repeats itself 30-ish times per an hour.

[Thu Aug 13 09:22:44.862756 2020] [:error] [pid 4194213] [client 172.69.71.93:51062] File does not exist: /home/*****/public_html/cron.php

As far as I can see, the client IP changes all the time. I'm using cron-jobs, but the files run are not at public_html folder. My cron jobs run every hour and the errors occurs all the time.

I think there might be just attacks against me all the time. Is there anything I can do? Or is there something wrong with my cron jobs?

The IP listed originates from CloudFlare, my assumption is you use CloudFlare on the domain, and your server is not using mod_remoteIP so you won't be able to identify where the traffic is originating from. The cron.php script is being called from somewhere what are the cron jobs you do have? You may want to contact your hosting provider to see if they have any further information on why the site is having the issues it is as well.

Yes, CDN is fixed with Cloudflare.

I'm using cron jobs, but nothing as I can understand, should refer to cron.php-file. Hosting provider said I should have a look on Cloudflare settings for this matter.
