Certificate problem with Let's Encrypt and Jitsi

Hi @ReinerD

can you post the output of:

ucr search --brief jitsi

I have it running with a separate apache vhost like:

<VirtualHost *:443>
        ServerName jitsi.myserver.org
        SSLEngine on
        SSLProxyEngine on
        SSLProxyCheckPeerCN off
        SSLProxyCheckPeerName off
        SSLProxyCheckPeerExpire off

        SSLCertificateFile /etc/univention/letsencrypt/signed_chain.crt
        SSLCertificateKeyFile /etc/univention/letsencrypt/domain.key

        ProxyPass / http://localhost:8888/ retry=0
        ProxyPassReverse / http://localhost:8888/
        ProxyPreserveHost On
        RequestHeader set X-Forwarded-Proto "https"
        RewriteEngine on
        RewriteCond %{HTTP:Connection} Upgrade [NC]
        RewriteCond %{HTTP:Upgrade} websocket [NC]
        RewriteRule ^/?(.*) "ws://127.0.0.1:8888/$1" [P,L]

</VirtualHost>

The LE-Cert is from the LE-univention-app.

Best, Bernd
