I would like to share a recurring problem I have been experiencing with my Apache server and seek help to resolve it. Here is the detailed breakdown of my situation:

Lately I have been running into intermittent problems with my OVH hosted Apache server. The specific error I find in the Apache error_log is “cannot find the IPv4 address of “stock.ovh”. To temporarily resolve this issue, I modified the hosts file by adding the word “stock.ovh” to the first line of my hosts file “127.0.1.1 vps-numversion.vps.ovh.net vps-numversion stock.ovh”. (numversion is my vps server version) This solution worked but next day the problem occurs again and I find that the modification I made to the hosts file is reverted i.e. the line I added disappears. (just the word stock.ovh)

This cycle of temporary resolution and recurrence of the problem is affecting the availability and performance of my web services hosted on the Apache server. Additionally, I have noticed that restarting the Apache server is essential for my web pages to work again.

I’ve checked the permissions on the hosts file and I have the appropriate privileges to edit it. However, it seems like something is automatically reverting my changes and I can’t identify the root cause of this behavior.

I would greatly appreciate any help, suggestions or advice to permanently resolve this issue and ensure the stability of my Apache server on OVH. If anyone has previous experience with these types of problems or knows of any potential solutions, I’d love to hear your thoughts.

It’s worth mentioning that I’m an OVH customer and I also have a VPS, and when websites go down they show a “Bad Gateway Error”.

Thanks in advance for your time and help!

PS Also, the information about the operating system and version of my system is as follows: Debian 3.16.81-1x86_64 GNU/Linux

I have tried modifying the hosts file on my server to resolve the name resolution issue I am experiencing with my Apache server in Plesk. I was hoping that adding the “stock.ovh” entry to the hosts file would temporarily resolve the issue and get my Apache server working properly again. However, after a day, I discovered that the modification I made to the hosts file had been automatically reverted, and the problem persists.
