nginx: configuration file /etc/nginx/nginx.conf test is successful
apache2ctl configtest

In /var/log/apache2/domains I found several times the following entry:
2021/06/13 11:27:24 [error] 10354#10354: *297 SSL_do_handshake() failed (SSL: error:1408F10B:SSL routines:ssl3_get_record:wrong version number) while SSL handshaking to upstream, client: xx.xx.xx.xx, server: , request: “GET /favicon.ico HTTP/2.0”, upstream: “https://xx.xx.xx.xx:8443/favicon.ico”, host: “www.”
For an 500 internal server error there should be a message - usualy it gets logged as soon as you request the related domain. Without any log informations, it’s hard to say what’s wrong - I can’t access your server from my side.
