    Because ISPConfig is running on port 8080 and not 443. So a vhost for port 443 should not be in this file.

    Besides that, you still did not answer my questions from post #14. I asked you 3 questions, you answered just 1. The reason for your problem seems to be that acme.sh fails because it can't find a service on port 80 on localhost (127.0.0.1) to do the LE authentication.

    It is a standalone server from server4you.de. No virtualization. Fresh install of Debian testing and of ISPConfig. Nothing else running on this server.
    Yes, I think that's the problem.
    Strange that when I'm doing a telnet it works kind of:
    sun:~# telnet localhost 80
    Trying 127.0.0.1...
    Connected to localhost.
    Escape character is '^]'.

    Seems to work:
    sun:~# nc -zv 127.0.0.1 80
    localhost [127.0.0.1] 80 (http) open

    And also here:
    sun:~# nmap -sS 127.0.0.1 -p 80
    Starting Nmap 7.91 ( https://nmap.org ) at 2020-12-13 15:24 CET

    Host is up (0.000036s latency).

    Now I can't access ISPConfig via rothmedia.net:8080 any more. Also because of the https issue.
    I can reach other websites via http.

    When I run
    sun:~# acme.sh --issue -d rothmedia.net -w /var/www/ispconfig/
    [Mon 14 Dec 2020 02:12:10 PM CET] Domains not changed.
    [Mon 14 Dec 2020 02:12:10 PM CET] Skip, Next renewal time is: Tue 09 Feb 2021 02:23:52 PM UTC
    [Mon 14 Dec 2020 02:12:10 PM CET] Add '--force' to force to renew.

    it looks like it works.
    My question then is the following: What problem has ISPConfig with it?

    Kind regards

    Before you fix that, it's worth asking if you are sure you want to use the domain name as your server name; normally you do not, as the domain will then be unusable within ispconfig for email, etc.

    Do you see the correct site, just wrong certificate? If so, check the symlinks in /use/local/ispconfig/interface/ssl/.

    You're right. Actually I changed the ispserver name to sun. Which means, it should be accessible via sun.rothmedia.net:8080.
    Under /usr/local/ispconfig/interface/ssl/ there are the certificates:
    sun:/usr/local/ispconfig/interface/ssl# ls -l
    total 32
    -rwxr-x--- 1 ispconfig ispconfig 45 Dec 13 19:49 empty.dir
    -rwxr-x--- 1 ispconfig ispconfig 1842 Dec 13 19:49 ispserver.crt
    -rwxr-x--- 1 ispconfig ispconfig 972 Dec 13 19:49 ispserver.csr
    -rwxr-x--- 1 ispconfig ispconfig 3311 Dec 13 21:47 ispserver.key
    -rwxr-x--- 1 ispconfig ispconfig 3311 Dec 13 19:49 ispserver.key.secure
    -rwxr-x--- 1 ispconfig ispconfig 3429 Dec 13 19:49 ispserver.pem
    -rwxr-x--- 1 ispconfig ispconfig 619 Dec 13 19:49 rothmedia.net.conf
    -rwxr-x--- 1 ispconfig ispconfig 208 Dec 13 19:49 rothmedia.net.csr.conf

    The ispconfig.crt is a letsencrypt one I could/would use if it would work.
    In the /etc/apache2/sites-available/ I have a rothmedia.net.vhost but not a sun.rothmedia.net.vhost, which I deleted before running ispconfig_update.sh --force. But it is not created new.
    I'm a bit confused now.
    I'm generating the letsencrypt certificate for rothmedia.net and not for the subdomain, correct?\
    But for apache I need a sun.rothmedia.net.vhost.

    The file sun.rothmedia.net.vhost is not related to ISPConfig GUI. Did you delete the ispconfig.vhost file manually as well? if yes, ispconfig will not recreate it on an update. If you made a backup, restore that file in sites-available folder and the symlink to the file in sites-enabled folder.

    I did it. I also commented out the NameVirtualHost, because apache was complaining about it.
    I restarted the service apache2 and tested the site. No success. I get the problem loading page error.
    with http://sun.rothmedia.net I get the default 'Welcome to your webpage' page.
    https://sun.rothmedia.net not working either.

    now I can access the ISPConfig Web Inteface again. :)
    Under https://rothmedia.net:8080 as well as https://sun.rothmedia.net:8080

    I have no clue how to fix the

    error. But I'm happy that I have it running with the self signed certificate at least.
    Thanks for all your help so far!

    To start, I think you haven't configured your hostname correctly as it should be a subdomain and not the root domain.

    Have you followed the Perfect Server tutorial closely? You might want to go through it again and follow the steps there with the same commands.

    From a quick search, the /dev/tcp/127.0.0.1/80 syntax is handled by the bash shell, perhaps you simply missed the step to reconfigure /bin/sh to be bash instead of dash?

    Yes. There are quite a few tutorials around. I found one which explains the hostname stuff, which I changed.
    I found another difference in the /etc/postfix/main.cf file:
    -o smtpd_client_restrictions=permit_sasl_authenticated,reject
    was missing. This line is missing at all. I added it.
    I also commented the following line
    #bind-address = 127.0.0.1
    although my SQL Server was running as expected.
    But anyways, my postfix, and all other services are working as expected.
    What I am missing ist mailman, because there is no install candidate for Debian testing.
    There is a mailman3-web package. But this wants to install a whole bunch of stuff, I don't think I need.

    Mailman 3 is not supported, it's basically a completely different software than the original mailman version. It is unlikely that we add support for it. If Mailman is a requirement for you, then you'll have to reinstall the system with a Debian version that ships with mailman like Debian 10.

    YES! That was the point with the error. Many thanks! I don't know how I could miss this. Ashes onto my head!
    Now the ispconfig_update.sh nags that letsencrypt could not issue a certificate for sun.rothmedia.net.
    Do I have to issue a certificate for every subdomain, or can I issue a certificate for the domain rothmedia.net and all the subdomains using this one, or do clients not trust the subdomains in this case?

    Many thanks for your quick reply. No, I don't need mailman.
    In the issuing certificate I proceeded one step. I missed to change the bash. See my post above.

    Now I have another problem with not being able starting apache2. It asks for the certificates passphrase. When I provide it, it comes up with this in the apache/error.log:
    SSL Library Error: error:0D0680A8:asn1 encoding routines:asn1_check_tlen:wrong tag
    SSL Library Error: error:0D08303A:asn1 encoding routines:asn1_template_noexp_d2i:nested asn1 error
    Quite a stony path to ISPConfig success.

    I would advice you to go through the perfect server tutorial again completely, eventually even reinstall the whole system. You missed several steps, which will cause more issues in the future.

    I just did it again. i can't reinstall because I have already clients using it with mail addresses...
    Do I have to create a subcomain for the ispconfig server name i.e. 'sun' in my case? sun.rothmedia.net. Thus letsencrypt can issue the certificate and not getting into the following error?
    sun.rothmedia.net:Verify error:Invalid response from http://sun.rothmedia.net/.well-known/acme-challenge/DYt7iA6-JcEyHR2syreIfN5rB5ZI4lpCPef

    Another success. Let's Encrypt certificates are now created direct through ISPConfig by pressing Let's Encrypt SSL. :)
    I created with acme.sh manually a certificate for rothmedia.net and placed it into /usr/local/ispconfig/interface/ssl/
    And no I can access ISPConfig via https//rothmedia.net:8080. Only when I want to access ISPConfig via sun.rothmedia.net:8080 I have to accept the certificate from rothmedia.net.

    You can manually re-request the certificate to include both names.
