Just upgraded to #Caddy 2.7.2 on FreshBSD.org. It didn't last very long:

Successfully started Caddy (pid=15076) - Caddy is running in the background

panic: runtime error: invalid memory address or nil pointer dereference

[signal SIGSEGV: segmentation violation code=0x1 addr=0x30 pc=0x907c10]

Looks like it's HTTP/3 related, which I've disabled for now: https://github.com/caddyserver/caddy/issues/5680

Imagine inventing a programming language in 2009 and it still does this sort of thing...
