Answer 1

I had the same issue. In my case I was using digitalocean and nginx.
I have first setup a domain example.app and a subdomain dev.exemple.app in digitalocean. Second,I purchased two ssl certificat from godaddy. And finaly, I configured two domain in nginx to use those two ssl certificat with the following snipet

My example.app domain config

    server {
    listen 7000 default_server;
    listen [::]:7000 default_server;

     listen 443 ssl default_server;
     listen [::]:443 ssl default_server;

    root /srv/nodejs/echantillonnage1;

    # Add index.php to the list if you are using PHP
    index index.html index.htm index.nginx-debian.html;

    server_name echantillonnage.app;
    ssl_certificate /srv/nodejs/certificatSsl/widcardcertificate/echantillonnage.app.chained.crt;
    ssl_certificate_key /srv/nodejs/certificatSsl/widcardcertificate/echantillonnage.app.key;

    location / {
            # First attempt to serve request as file, then
            # as directory, then fall back to displaying a 404.
            proxy_pass http://127.0.0.1:8090;
            proxy_http_version 1.1;
            proxy_set_header Upgrade $http_upgrade;
            proxy_set_header Connection 'upgrade';
            proxy_set_header Host $host;
            proxy_cache_bypass $http_upgrade;
    #try_files $uri $uri/ =404;
    }
 }

My dev.example.app

   server {
    listen 7000 default_server;
    listen [::]:7000 default_server;

     listen 444 ssl default_server;
     listen [::]:444 ssl default_server;

    root /srv/nodejs/echantillonnage1;

    # Add index.php to the list if you are using PHP
    index index.html index.htm index.nginx-debian.html;

    server_name dev.echantillonnage.app;
    ssl_certificate /srv/nodejs/certificatSsl/dev/dev.echantillonnage.app.chained.crt;
    ssl_certificate_key /srv/nodejs/certificatSsl/dev/dev.echantillonnage.app.key;

    location / {
            # First attempt to serve request as file, then
            # as directory, then fall back to displaying a 404.
            proxy_pass http://127.0.0.1:8091;
            proxy_http_version 1.1;
            proxy_set_header Upgrade $http_upgrade;
            proxy_set_header Connection 'upgrade';
            proxy_set_header Host $host;
            proxy_cache_bypass $http_upgrade;
    #try_files $uri $uri/ =404;
    }
 }

When I was launching https://dev.echantillonnage.app , I was getting

    Fix CURL (51) SSL error: no alternative certificate subject name matches

My mistake was the two lines bellow

    listen 444 ssl default_server;
     listen [::]:444 ssl default_server;

I had to change this to:

     listen 443 ssl;
     listen [::]:443 ssl;
