Once you complete the change I described to your default VirtualHost in ssl.conf that warning message will change. It will be more obvious that you can ignore it.
The warning is because that default VHost uses a self-signed cert and the domain name in it does not match the ServerName. It still won't after you make the change I described. And that is fine. The message just won't look like something is wrong with your actual aewa VirtualHost and certs.
No, maybe I misunderstand what you mean but I didn't see a line like that in your ssl.conf file that you showed in post #5
Have you changed that file since then? If so, please show it again.
If not, just carefully re-read my post #10 that, in summary, says to change this line in ssl.conf
#ServerName www.example.com:443
to exactly this (note no longer commented out)
ServerName default.aewa.domain
Do Not use a valid ServerName in that ssl.conf default VirtualHost. You can only properly use a domain name in one VHost for a specific port. Using a valid name in that default VHost creates a duplicate. Sadly, Apache does not warn about this except that it won't always produce the correct results.
You don't normally specify a port with ServerName (anywhere) but that isn't the essential bit here.
Please show ssl.conf again. Line #40 should not be using www.aewa.org. You already use that domain as a ServerAlias in the VirtualHost in this file /etc/httpd/conf.d/aewa.org-le-ssl.conf and it is working correctly. You can't have the same domain using the same port twice.

# o ExportCertData:
# This exports two additional environment variables: SSL_CLIENT_CERT and
# SSL_SERVER_CERT. These contain the PEM-encoded certificates of the

# authentication is used). This can be used to import the certificates
# into CGI scripts.
# o StdEnvVars:
# This exports the standard SSL/TLS related `SSL_*' environment variables.
# Per default this exportation is switched off for performance reasons,
# because the extraction step is an expensive operation and is usually
# useless for serving static content. So one usually enables the
# exportation for CGI and SSI requests only.
# o StrictRequire:
# This denies access when "SSLRequireSSL" or "SSLRequire" applied even
# under a "Satisfy any" situation, i.e. when it applies access is denied
# and no other module can change it.

# This enables optimized SSL connection renegotiation handling when SSL

# SSL Protocol Adjustments:
# The safe and default but still SSL/TLS standard compliant shutdown
# approach is that mod_ssl sends the close notify alert but doesn't wait for
# the close notify alert from client. When you need a different shutdown
# approach you can use one of the following variables:
# o ssl-unclean-shutdown:
# This forces an unclean shutdown when the connection is closed, i.e. no
# SSL close notify alert is sent or allowed to be received. This violates
# the SSL/TLS standard but is needed for some brain-dead browsers. Use
# this when you receive I/O errors because of the standard approach where
# mod_ssl sends the close notify alert.
# o ssl-accurate-shutdown:
# This forces an accurate shutdown when the connection is closed, i.e. a
# SSL close notify alert is sent and mod_ssl waits for the close notify
# alert of the client. This is 100% SSL/TLS standard compliant, but in
# practice often causes hanging connections with brain-dead browsers. Use
# this only for browsers where you know that their SSL implementation
# works correctly.
# Notice: Most problems of broken clients are also related to the HTTP
# keep-alive facility, so you usually additionally want to disable
# keep-alive for those clients, too. Use variable "nokeepalive" for this.
# Similarly, one has to force some clients to use HTTP/1.0 to workaround
# their broken HTTP/1.1 implementation. Use variables "downgrade-1.0" and
# "force-response-1.0" for this.

That looks good. It is strange the DUMP_VHOSTS output still showed www.aewa.org in your ssl.conf. You are using a very old version of Apache so maybe that is affecting it. In any case, that default VHost now won't be able to cause confusion with Certbot at least.
Let's see if we can cleanup yukla27. Please show the contents of these two files. There is a duplication of name and port here too.
Okay, we can remove a number of problems just by modifying yukla27.org.conf
That config file has a VHost for port 80 with a redirect with a faulty format. It would not work so is a good thing it is not being selected by Apache with the current layout.
It also has a VHost for port 443 that duplicates an earlier VHost. And, its redirect is also incorrect. It would cause a loop if it was activated because it would redirect an HTTPS request to itself.
To fix all of that change yukla27.org.conf to look like below. In its entirety. Nothing more nothing less. There are actually several changes to the VHost for port 443 so be careful when making the change.
The end result is that this VHost for yukla27.org will be the same as for www.yukla27.org except they each use their own cert file.
<VirtualHost *:443>
ServerName yukla27.org

All HTTP and HTTPS requests look good for all your domain names - aewa and yukla27 both the bare domain and the www domain.
The HTTP requests get redirected to HTTPS as is recommended. The HTTPS requests all use a certificate with the proper domain name. This is all good.
There is a further refinement to combine the two VirtualHost for yukla27 and www.yukla27 into one. But, I don't see a strong need to do that.
Currently they are in separate VHosts with separate certs. There is nothing technically wrong with that. And, given how simple the VHost configs are that doesn't seem like an admin burden. The effort to combine them would produce little to no added value.
Before concluding though we should check that the auto-renew would work for all of them. Please show output of this. Note the --dry-run will not disturb your existing production certs. It is just a test
