I see that I need start nginx manually after restart debian11.

I restart nginx from hestia and all work good up to next debian restart

Check if the ip address is still available via ip addr if yes run:
sysctl -w net.ipv4.ip_nonlocal_bind=1

if no

v-update-sys-ip if you have a dynamic ip address

3

I use vps from linode. Address is not changing or I dont understand you

4

Then run::

sysctl -w net.ipv4.ip_nonlocal_bind=1

and restart Nginx

5

the problem appears only when starting debian and does not appear during normal operation or restarting nginx

may I need edit the /etc/sysctl.conf or do something else?

6

Yes:

sysctl -w net.ipv4.ip_nonlocal_bind=1

Should solve the issue or change it in /etc/sysctl.conf

7

I make

sysctl -w net.ipv4.ip_nonlocal_bind=1

and restart debian. nginx is error and not started. I need to make “service start nginx” manually

then I add to the end of /etc/sysctl.conf

net.ipv4.ip_nonlocal_bind=1

and restart debian. Nginx started successfully. Only one line confuses:

“isp.domain.com systemd[1]: nginx.service: Can’t open PID file /run/nginx.pid (yet?) after start: Operation not permitted”

Is my solution correct or should I have done it differently, for example adding a line to a separate file, for example /etc/sysctl.d/99-custom.conf ?
