Http-01 Challenge failed and Connection refused

I just bought a new server, and want to follow this for www.pretty-formula.com. After putting pretty-formula.com in related files, I got this error:

IMPORTANT NOTES:
 - The following errors were reported by the server:

   To fix these errors, please make sure that your domain name was
   entered correctly and the DNS A/AAAA record(s) for that domain
   contain(s) the right IP address. Additionally, please check that
   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.

### Reloading nginx ...
cannot exec in a stopped state: unknown

Here is the record I added to pretty-formula.com:

It’s a very new domain, I don’t understand what’s blocking.

Thank you

[ahaw021]

you are using the HTTP Challenge instead of the DNS Challege

Specify the DNS Challenge and you should be able to set it up

Here is the reference https://certbot.eff.org/docs/using.html#manual

@ahaw021 Why would you suggest changing from a relative easy challenge to a relative hard challenge? Personally, I don’t see any reason to use the dns-01 challenge at this stage.

@chengtie Do you actually use docker on your server? Or is it just for this script?

[chengtie]

It is a new server, and I want to implement this website with docker+nginx+letsencrypt.

[Osiris]

OK. Well, I’m not a big fan of the script you’ve posted, but I personally don’t have any docker experience what so ever.

Firstly, please set the staging variable in the script to 1 for the time being while you’re still testing it out.

Secondly, from the last line, it looks like your nginx docker container didn’t really start properly. Perhaps you could debug that first separately from the script: does the nginx docker container even work?
