Matrix synapse federation not possible

I successfully set up my homeserver based on the description available in https://linuxhandbook.com/install-matrix-synapse-docker/ using a docker image.

I had to change it a little bit, as I am using Apache as a reverse proxy. This I made from another example:

<VirtualHost *:443> 
    SSLEngine on 
    ServerName matrix.oe8bck.at

    Include /etc/letsencrypt/options-ssl-apache.conf
    SSLCertificateFile /etc/letsencrypt/live/...
    SSLCertificateKeyFile /etc/letsencrypt/live/...

    RequestHeader set "X-Forwarded-Proto" expr=%{REQUEST_SCHEME}
    AllowEncodedSlashes NoDecode
    ProxyPreserveHost on
    ProxyPass /_matrix http://127.0.0.1:8008/_matrix nocanon
    ProxyPassReverse /_matrix http://127.0.0.1:8008/_matrix
    ProxyPass /_synapse/client http://127.0.0.1:8008/_synapse/client nocanon
    ProxyPassReverse /_synapse/client http://127.0.0.1:8008/_synapse/client

    <IfModule security2_module>
      SecRuleEngine off
    </IfModule>

</VirtualHost>

<VirtualHost *:8448>
    SSLEngine on
    ServerName oe8bck.at

    Include /etc/letsencrypt/options-ssl-apache.conf
    SSLCertificateFile /etc/letsencrypt/live/...
    SSLCertificateKeyFile /etc/letsencrypt/live/...

    RequestHeader set "X-Forwarded-Proto"expr=%{REQUEST_SCHEME}
    AllowEncodedSlashes NoDecode
    ProxyPass /_matrix http://127.0.0.1:8008/_matrix nocanon
    ProxyPassReverse /_matrix http://127.0.0.1:8008/_matrix

    <IfModule security2_module>
      SecRuleEngine off
    </IfModule>

</VirtualHost>

I checked the TLS certificate, it is valid. But the federation does not work! I checked it with https://federationtester.matrix.org/api/report?server_name=matrix.oe8bck.at but I cannot see the reason for these errors:

"Message": "Get \"https://88.116.94.22:8448/_matrix/key/v2/server\": dial tcp 
88.116.94.22:8448: connect: connection refused"
  "error": "Get \"matrix://matrix.oe8bck.at/_matrix/federation/v1/version\": dial tcp 88.116.94.22:8448: connect: connection refused"

Maybe somebody can help me?

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
