Let's Encrypt certificate for site alongside Jitsi Meet - ssl

Question

I've a server running Ubuntu 18.04 and Nginx and have a fully functioning instance of Jitsi Meet hosted on it.
On the other hand I have 2 other sites (one a react front end and the other a backend) and i need them to have ssl certificates since we are using Jitsi Meet api from the front end and chrome is not letting us give permissions on the mic and camera because the front end is not secure.
So I tried installing certbot and getting a Let's Encrypt certificate but when i get it and try to restart nginx, it fails.
I think it has something to do with Jitsi using the port 443 or something but I really can't tell...
This is the nginx conf for jitsi domain:

this is the nginx conf for the front end domain:

server_name app.<base-domain> www.app.<base-domain>;
listen 80;
return 404; # managed by Certbot
}
this is the nginx error.log:

I was hoping someone can tell how I should configure this in order to have both jitsi and the front end secure.
I also will add that both domains are actually subdomains... meaning jitsi domain is video..com
and front is app..com
the real config has base-domain and paths correctly specified... If I remove all ssl config from the front end nginx configuration, everything work again.

Answer 1

You should use devops-guide-quickstart . There is Generate a Let's Encrypt certificate section. If you have nginx on your system before installing jitsi, jitsi will run with its nginx configuration.
if you need customized nginx file, here it is. But you should work on for security concerns.
** For standalone(without Docker) remove
"resolver 127.0.0.1 valid=5s ipv6=off;"
then change rest of 127.0.0.1 to localhost

Also this configuration will be stuck on CSP error. Just for test developments this code will allow all CSP risks. you can add under the
ssl_session_cache shared:SSL:50m;
set $CSP_image "img-src 'self' 'unsafe-inline' 'unsafe-eval' data: *.printfriendly.com *.w.org *.gravatar.com *.vimeocdn.com; ";
set $CSP_script "script-src 'self' 'unsafe-inline' 'unsafe-eval' *.w.org *.gravatar.com *.googleapis.com *.jsdelivr.net *.printfriendly.com *.kxcdn.com *.vimeocdn.com *.hs-analytics.net *.securitymetrics.com *.google-analytics.com; ";
set $CSP_style "style-src 'self' 'unsafe-inline' *.googleapis.com *.bootstrapcdn.com *.gstatic.com *.vimeocdn.com; ";
set $CSP_font "font-src 'self' data: *.googleapis.com *.bootstrapcdn.com *.gstatic.com *.googleapis.com; ";
set $CSP_frame "frame-src 'self' *.vimeocdn.com *.vimeo.com; ";
set $CSP_object "object-src 'self' ; ";
set $CSP "default-src 'self' ; ${CSP_image} ${CSP_script} ${CSP_style} ${CSP_font} ${CSP_frame} ${CSP_object}";
add_header Content-Security-Policy $CSP;
