Migrating from AWS to Vultr - Unable to install the certificate

What online tools to you recommend to check if port 80 works.

Also should I revert what I did with ufw


sudo ufw delete 80/tcp : it think this is how to revert it, and of course the same to 433 (which should of been 443)

Not sure what you mean by is the site enabled? I know that the nginx directory /etc/nginx/sites-enabled/ is empty.

For use of both names, first ensure both names resolve via DNS.
Then in both blocks:

server_name band-manager.ca;

Should be:

server_name band-manager.ca;
server_name www.band-manager.ca;

and change:

    if ($host = band-manager.ca) {
        return 301 https://$host$request_uri;
    } # managed by Certbot

to just:

return 301 https://$host$request_uri;

Okay that was it, now I remember what happened. When I went to configure sites-available I wiped the original config with rm /etc/nginx/sites-available/default. Then wrote my own server block. I think at some point in this time I accidentally rm /etc/nginx/sites-enabled/default as well, which I never usually touch when i set up my servers. Without that file it was preventing nginx from running properly.

Thanks @rg305 @JuergenAuer for helping me figure this out. I didn’t know about the sites-enabled file until this time around setting up the Vultr server.


Also thanks to @_az aswell for helping me figure out how to run the certbot without prompts, would of thanked you in the last message, but I can only mention two users per post and a new user.

Now you have a minimal working configuration.

But the redirect http -> https doesn’t work - Grade H. So users have the insecure version.

There is content with JavaScript:

and an Express server header.

X-Powered-By: Express

Same checking http + /.well-known/acme-challenge/unknown-filename with a wrong http status 200. A http status 404 - Not Found - is expected.

Thanks for showing me this tool: https://check-your-website.server-daten.de/?q=band-manager.ca

I’m looking further into this issue, my understanding of Nginx and SSL if still very limited. Checking out my sites-available and sites-enabled I’ve notice certbot did not update the sites-available default file after running it. Comparing the Vultr server to my Digital Ocean Nginx config where certbot seemed to work fine, the sites-enabled file is quite different.

Digital Ocean Server: /etc/nginx/sites-enabled/default certbot worked

server {
    server_name wescoderre.dev;
    location / {
        proxy_pass http://localhost:9000;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header Host $host;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";

    listen 443 ssl; # managed by Certbot
    ssl_certificate /etc/letsencrypt/live/wescoderre.dev/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/wescoderre.dev/privkey.pem; # managed by Certbot
    include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot


server {
    if ($host = wescoderre.dev) {
        return 301 https://$host$request_uri;
    } # managed by Certbot

    listen 80;
    server_name wescoderre.dev;
    return 404; # managed by Certbot


Vultr Server: /etc/nginx/sites-enabled/default certbot is havign troubles here

server {
    listen 80;
    server_name band-manager.ca;
    location / {
        proxy_pass http://localhost:5050;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header Host $host;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";

    listen 443 ssl; # managed by Certbot
    ssl_certificate /etc/letsencrypt/live/band-manager.ca/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/band-manager.ca/privkey.pem; # managed by Certbot
    include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot


I’ll be setting up that X-Powered-By: Express header, and downloaded an Nginx cookbook to learn a little more about its setup.

I feel like all this trouble stems from me deleting sites-enabled accidentally while setting up the server.

The DO config is much simpler and should be easy to understand/use/modify.
The Vultr config is complicated and makes it more difficult to modify.

I ended up using the DO config on my Vultr server. For some reason cerbot just wouldn’t update my Nginx the same way as it did on Amazon EC2 or Digital Ocean, on this new server.

Because it is difficult to correctly update both HTTP and HTTPS in one block (even for a human).

Glad to hear it worked out thou :slight_smile:
