and then all of it stopped

my vm is installed on google vm

and it was working well till i cleared all cache can anybody find a solution or has anyone fallen on the same probelm ?

Mmm Hello, you used the plugin [hestia nginx cache] (Результаты поиска «hestia-ninx-cache» | WordPress.org Русский)? You correctly set up the API and introduced it to the exception of 127.0.0.1 and your IP, what do your Nginx logs say?

yes i used all documentation needed i think as i found here it is

Signal 9 is SIGKILL so something is killing the processes, usually it could be because OOM (Out Of Memory) so the OS is killing the processes.

Do you have enough free RAM?

free -h

Check whether OS is killing the processes:

sudo dmesg | grep -i kill

yes i had free ram it was just that the plugin made bad configuration at sudo nano /home/admin/conf/web/website ( my website ) /nginx.conf

i checked the listen and proxy and changed it to my ip’s

i checked that the nagnix is well working and then restarted it

all thank to gemini <3
and to you
