"Some challenges have failed." when using Certbot

Help
1

My domain is:
velcoro.xyz

I used docker-compose, which ran Nginx proxy server, my ASP.NET Core app and Certbot.
Then I got from Certbot following response:

Hi @Yehor

there is a check of your domain, ~~ one hour old - https://check-your-website.server-daten.de/?q=velcoro.xyz

That's a parking page, not your webserver.

And non-www / www have different ip addresses, that can't work if you use a simple http validation.

So first step: Update your dns, so your A entries have the ip address of your server.

PS: You must be the domain owner of that domain. It's not enough to create a local system and use a domain name you don't own.

Thanks for the reply. I’ll try to update the dns. I’m the owner as well. Probably I set it up in a wrong way.

I managed to add A records. Seems like it worked. But I got a problem with the following error:

“Timeout during connect (likely firewall problem)”

I read that there are some ports should be opened. What ports should be opened exactly? And where? Locally or inside docker container?

Please learn some basics:

And something about Challenge types:

A working port 80 webserver is required, not a timeout.

Rechecked your domain - velcoro.xyz - Make your website better - DNS, redirects, mixed content, certificates - only timeouts, that can't work.
