Hallo to the Forum,
i will use an Apache2 Server as an Reverse Proxy for my Exchange Server.
After i make the Apache Config, i will create an LE Cert.
In the Apache2-Config:
define FrontEndServerName srv.domain.de
define FrondEndServerAlias srvdomain.de
define FrontEndServerAdmin email@example.com
define BackEndServerIP 192.xxx.xxx.xxx (Interne IP Exchange Server)
Create Zert: certbot --apache
It shows me:
Which names would you like to activate HTTPS for?
Select the appropriate numbers separated by commas and/or spaces, or leave input
blank to select all options shown (Enter 'c' to cancel):
I take "1". Then it shows me:
Waiting for verification...
Challenge failed for domain srv.domain.de
http-01 challenge for srv.domain.de
Cleaning up challenges
Some challenges have failed.
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
PLEASE, HELP ME. Whats wrong?
