@justoverclock All done. Both https://vfgest.it and https://vfgest.it should work now
You have to adjust certbot for this to work - see below command transcript executed on your host
root@vito-fiore:/etc/nginx/sites-enabled# sudo certbot

Which names would you like to activate HTTPS for?
We recommend selecting either all domains, or all domains in a VirtualHost/server block.

You have an existing certificate that contains a portion of the domains you
requested (ref: /etc/letsencrypt/renewal/vfgest.it.conf)
It contains these names: vfgest.it
You requested these names for the new certificate: vfgest.it, www.vfgest.it.
Do you want to expand and replace this existing certificate with the new
certificate?

@justoverclock You can drop the vfgest conf file as it’s not being used
@phenomlab thank you very much!!!
@justoverclock Anytime
@justoverclock You should change your app so that it only listens on localhost or 127.0.0.1 for security reasons as you are currently exposing it publicly via port 8080. The reverse proxy means that this is not required, as nginx redirects it for you and is fully secure.
@phenomlab so now this app use a server created by me with nodejs…so all the api endpoints are available through port 3030
can i set the env variable to https://vfgest.it:3030 ?
@justoverclock If the app is listening on 8080, which it typically would, then no, leave it alone. Are the endpoints intended to be public ? Typically, these aren’t accessible via nginx
@phenomlab if now i try to login, the endpoint of my api doesn’t work because of mixed content
Mixed Content: The page at 'https://vfgest.it/' was loaded over HTTPS, but requested an insecure XMLHttpRequest endpoint 'http://MYSERVERIP:3030/api/login'. This request has been blocked; the content must be served over HTTPS.
@justoverclock Yes, that’s expected. You should change your endpoint so it works over https otherwise it won’t be secure, and is then subject to eavesdropping as the traffic is being sent in clear text. From a security standpoint, this is an absolute no.
@phenomlab ok, so i can add https, can i leave the ip or i need to add vfgest.it:3030?
@justoverclock You can use either, but if the API is not meant to be exposed publicly, and should only be accessed by the app itself, then you should use 127.0.0.1. Ultimately, the design is up to you.
@phenomlab well, i’ve learned something new, no its a private crm developed by me, so no external use 
@justoverclock Exactly - that’s why I asked You won’t be exposing the API then. Any issues, let me know.
@phenomlab ok i’ll try later when people are not using the crm :P, and i’ll post here the result 
@justoverclock No problems.
undefined phenomlab has marked this topic as solved on

@phenomlab its odd but doesn’t work if i use https://vfgest.it:3030 or https://SERVERIP:3030 or https://127.0.0.1:3030
must be something related to proxy…because server and client are on the same server…but works if i restore all to previous unsecure http connection
@justoverclock i’ve found an article that says
To resolve your issue you can setup nginx to proxy your http backend urls via https. With nginx server you will need to call your api like https://your_domain/api/some_path and nginx will proxy your request to api host, that you will set in config
so my server actually is on port 3030, what should i do?
thx!
@justoverclock ok i’ve found the solution by myself watching your files…
-i’ve created a subdomain
all works fine 
@justoverclock Beat me to it ! I was going to say that you could add another server block to the existing configuration, so for example
location /api {
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_set_header X-NginX-Proxy true;
proxy_pass http://127.0.0.1:3030/;
proxy_redirect off;
# Socket.IO Support
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
}@phenomlab 
i’m learning ahahahah
