time out when creating certificate  
I have my domain pointed to a machine with Ubuntu 20.4 with nginx and node, when I try to run the command to create the certificate, certbot creates the file in the directory, I can access the file through the browser before it is deleted by certbot  
but it returns me in the certbot timeout  
Certbot failed to authenticate some domains (authenticator: webroot). The Certificate Authority reported these problems:  
Domain: backend.pulsechat.com.br  
Type: connection  
Detail: 179.34.51.195: Fetching [http://backend.pulsechat.com.br/.well-known/acme-challenge/9Axq8xuVJ7o8FT7SuXuRMYNCDAzhvIk\_1GbGDFQGLOQ:](http://backend.pulsechat.com.br/.well-known/acme-challenge/9Axq8xuVJ7o8FT7SuXuRMYNCDAzhvIk_1GbGDFQGLOQ:) Timeout during connect (likely firewall problem)

I don't know what to do anymore, I disabled the server's firewall, pointed out ports on the modem (443,80,25,8080 etc)  
Any light on what I can do?  
Command I ran (test mode):  
sudo certbot Certonly --dry-run --webroot -w /etc/certificados/ -d backend.pulsechat.com.br -d pulsechat.com.br

Have you tried accessing your domain from the public internet?

Because I can't see it from my own USA-based server. The Let's Debug test site ([https://letsdebug.net](https://letsdebug.net)) cannot see it. And of course Let's Encrypt itself cannot.

This means that either no one can access your site from the public internet. Or, maybe you have a firewall blocking access outside your region or country.

Try a mobile phone with wifi disabled when you check if the challenge file exists.

Try adding these options to your command to give you more time to check the file

```nohighlight
sudo certbot Certonly --debug-challenges -v --dry-run --webroot -w /etc/certificados/ -d backend.pulsechat.com.br -d pulsechat.com.br

```
