Unable to get a new cert using cert bot

Getting the below error when trying to renew the cert for the domain.
the server could not connect to the client to verify the domain timeout

My domain is: telemetry.blueprism.it

I ran this command: sudo certbot renew --cert-name telemetry.blueprism.it -a webroot -w /var/www/html1/ --dry-run

It produced this output: Processing /etc/letsencrypt/renewal/telemetry.blueprism.it.conf

    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.

Hi @Bob403020

there is a check of your domain, 20 minutes old - https://check-your-website.server-daten.de/?q=telemetry.blueprism.it

Only timeouts:

Domainname Http-Status redirect Sec. G
http://telemetry.blueprism.it/ 52.142.117.156 -14 10.026 T
Timeout - The operation has timed out
https://telemetry.blueprism.it/ 52.142.117.156 -14 10.046 T
Timeout - The operation has timed out
http://telemetry.blueprism.it/.well-known/acme-challenge/check-your-website-dot-server-daten-dot-de 52.142.117.156 -14 10.027 T
Timeout - The operation has timed out

If you want to use webroot as authenticator, you use http validation. So an open port 80 is required.

Works http internal?

curl http://telemetry.blueprism.it/
curl http://telemetry.blueprism.it/.well-known/acme-challenge/1234

If yes, it’s a firewall- or routing problem.

Hi @JuergenAuer - I can confirm that port 80 is open and still getting the same issue, when you say that the domain timeout, I did check on the site, to see if I could find the problem, but it still shows the same error, When you say routing problem, is there steps I can take to see where it fails, like on windows there is a traceroute option.
