curl -H "X-Forwarded-For: 1.2.3.4" https://example.com

doesn't work for cloudflare proxied domain if it is specifically removed.

We may be still able to "workaround" it by connecting directly to the server.

curl -H "X-Forwarded-For: 1.2.3.4" --resolve example.com:443:$SERVER_IP https://example.com

UUID=XXXX-XXXX  /mnt/media  exfat  defaults,nofail,uid=1000,gid=1000,umask=0022  0  2

sudo rm -rf /run/systemd-journal-gatewayd.sock
sudo touch /run/systemd-journal-gatewayd.sock

vim /lib/systemd/system/systemd-journal-gatewayd.socket
