Fail: Install Zabbix 5.0 / nginx and Certbot

[mpmichael]

Hello,

on a new Ubuntu 20.04. Server I tried to Install Zabbix 5.0. MYSQL and NGINX is installed. Zabbix is installed as recommended at "Download Zabbix".
Zabbix ist setted up correctly and running under http. No I tried to use Certbot for issuing a SSL-Cert. But this failed with Error 404 Site not found (/.well-known/....)
After that I added in /etc/zabbix/nginx.conf

location ^~ /\.well-known/ {
alias /usr/share/nginx/html/.well-known/;
} 

but same Problem...

DNS is checked and fine.

Does anyone have a better Idea or could help?
thanks
Martin

I'll take that seriously and answer that the first thing you want do to is change if you're doing a default zabbix installation:

location ^~ /\.well-known/ {
alias /usr/share/nginx/html/.well-known/;
}

to

location ^~ /zabbix/ {
alias /usr/share/nginx/html/zabbix/;
}

Hello,

thank you for the answer. I oly posted the Part in nginx.conf that I changed. I used

apt-get install zabbix-nginx-conf

for the nginx setup.

The complete file is:

Hello,

the Problem is solved! It was a User mistake!
I forgot to add the Folder. After:

mkdir /usr/share/nginx/html/.well-known

it worked and certbot runns did the new Cert.
Thanks to all for the help!
