Following problem:
With firewall we get invalid Port in redirect target. Without Firewall we can connect to /.well-known/acme-challange/test. The certbot-auto certonly command was running without the fierewall.

My domain is: itnn-db-test.de

I ran this command: certbot-auto certonly --webroot --webroot-path /usr/share/tomcat/webapps/ROOT -d itnn-db-test.de

It produced this output:
Type: unauthorized
Detail: Invalid response from
http://itnn-db-test.de/.well-known/acme-challenge/B0Q6ZE9Iwb8Yo-eCQTj5GXcaQgN7VczH41goCu20144
[178.254.33.168]: “\n\n404 Not
Found\n\n

Not Found

\n<p”

My web server is (include version):
Apache Tomcat 7.0.76

The operating system my web server runs on is (include version):
Centos 7

My hosting provider, if applicable, is:
1blu.de

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

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

The version of my client is (e.g. output of certbot --version or certbot-auto --version if you’re using Certbot): certbot 0.40.1

Hi @mtheis

checking your domain there is a redirect to port 8443 - https://check-your-website.server-daten.de/?q=itnn-db-test.de

• http://itnn-db-test.de/.well-known/acme-challenge/check-your-website-dot-server-daten-dot-de
178.254.33.168

	https://itnn-db-test.de:8443/.well-known/acme-challenge/check-your-website-dot-server-daten-dot-de
	0.063

Letsencrypt doesn't follow redirects to non-standard-ports. So that can't work. Remove that redirect, minimal, if the subdirectory starts with /.well-known/acme-challenge.

But curious: That error isn't visible, there is a http status 404 - Not Found visible.

Next curious thing:

https://itnn-db-test.de:8443/.well-known/acme-challenge/check-your-website-dot-server-daten-dot-de

answers with a Tomcat http status 404 - Not Found.

So first question: Is

/usr/share/tomcat/webapps/ROOT

correct?

Create the two required subdirectories

/usr/share/tomcat/webapps/ROOT/.well-known/acme-challenge

there a file (file name 1234), then try to load that file via

http://itnn-db-test.de/.well-known/acme-challenge/1234

That must work, if your webroot is correct.
