Google Domains - Is it supported?

Having a difficult time getting things to work with a new .dev domain with a self hosted server (virtual host on proxmox). I seem to be able to connect to port 80 OK using my domain and request pages. I also verified 443 works (temporarily set it internally to port 80). I thought I read Google Domains might be the issue?

Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g., so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is:

I ran this command:
sudo certbot --nginx -d

It produced this output:

Challenge failed for domain

Cleaning up challenges
Some challenges have failed.


  • The following errors were reported by the server:

    Type: connection
    Detail: Fetching
    Timeout during connect (likely firewall problem)

    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.

My web server is (include version):

The operating system my web server runs on is (include version):
Ubuntu 20.04 server

My hosting provider, if applicable, is:

I can login to a root shell on my machine (yes or no, or I don't know):

I'm using a control panel to manage my site (no, or provide the name and version of the control panel):

The version of my client is (e.g. output of certbot --version or certbot-auto --version if you're using Certbot):

certbot 0.40.0

Hello @nobody205,

I'm afraid your site is not accessible from internet.

$ curl -IkL
curl: (7) Failed to connect to port 80: Connection timed out

What did you read? The only special thing about dev domains is that dev tld is preloaded into HSTS (forcing HTTPS) but that only affects browsers, it doesn’t affect to Let's Encrypt.

You should check whether your are forwarding the right ports to the right server and/or that your firewall is configured correctly.


I am not able to access it either - are you testing using localhost?

My fault. I checked again from an outside source and port 80 is blocked by my provider. I will try DNS challenges. I guess it's my only alternative.
