Hello everyone, I installed ISPconfig with nginx following every step of the tutorial "The Perfect Server - Debian 10 (Nginx, BIND, Dovecot, ISPConfig 3.1)" and secured it afterwards with the tutorial "Securing ISPConfig 3.1 With a Free Let's Encrypt SSL Certificate" and everything seems to work like expected with two exceptions: I cannot reach roundcube and phpmyadmin. Using the internal links serveradress:8080/phpmyadmin and serveradress:8080/webmail gives me 404 errors. If I change 8080 to 8081 like I read here in other posts, my browsers get the following error SSL_ERROR_RX_RECORD_TOO_LONG. Is there anything I missed or a way to fix this? I really hope someone can help me out here. Every hint is appreciated.
