Why are you running calibre-server from port 80?

Thank you for pointing me in right direction, yourrable.

Strangely I'm experiencing more problems. I simply can't start calibre server. Here's the error

user@xxx:~$ sudo systemctl status calibre.service
● calibre.service - Calibre Service
   Loaded: error (Reason: Invalid argument)
   Active: inactive (dead)

My configuration is as follow

[Unit]
Description=Calibre Service
After=network.target

[Service]
Type=simple
User=xxx
Group=calibre

ExecStart=/usr/bin/calibre-server\
--max-opds-items=30\
--max-opds-ungrouped-items=100\
--port 8282 \
--log=/logfile/.log \
--enable-auth \
--ssl-keyfile /etc/letsencrypt/live/domain/privkey.pem \
--ssl-certfile /etc/letsencrypt/live/domain/fullchain.pem \

"/path/to /library"

[Install]
WantedBy=multi-user.target

I'm really puzzled right now.
