My domain is: dev.bookshelf.sun-asterisk.ph

I ran this command: sudo ./init-letsencrypt.sh

It produced this output:

   your computer has a publicly routable IP address and that no
   firewalls are preventing the server from communicating with the
   client. If you're using the webroot plugin, you should also verify
   that you are serving files from the webroot path you provided.

Hi @CharlotteDS

there is a check of your domain, two days old - https://check-your-website.server-daten.de/?q=dev.bookshelf.sun-asterisk.ph

Domainname Http-Status redirect Sec. G
• http://dev.bookshelf.sun-asterisk.ph/
104.248.152.54 -2 1.800 V
ConnectFailure - Unable to connect to the remote server
• https://dev.bookshelf.sun-asterisk.ph/

ConnectFailure - Unable to connect to the remote server

Only blocked connections.

If you want to use http validation, a running webserver and an open port 80 are required.

http://dev.bookshelf.sun-asterisk.ph/.well-known/acme-challenge/random-filename

should answer with a http status 404 - Not Found.

I only followed this article: https://medium.com/@pentacent/nginx-and-lets-encrypt-with-docker-in-less-than-5-minutes-b4b8a60d3a71.

I already have a working application. I added a link between my app and nginx in the docker-compose.yml.

There

is another user. Same tutorial, same problem.

Perhaps the tutorial is incomplete.

I already solved the issue.
I accidentally erased a word in the configuration file.
