Link request error on fresh installation

[sbamamoto]

Hi,

I am trying to run signal-cli on debian bookworm with Java21. Server has no proxies but I got this:
`root@debian-4gb-hel1-2:/opt/signal-cli-0.13.18/bin# ./signal-cli link --name mucvce

sgnl://linkdevice?uuid=_osVLLSBlO7b2G-dgN1EYg%3D%3D&pub_key=BQ4W2LrCmkudEVR8et29Xa6YNGzb9KTbFWl57%2Bv%2F%2F1Za

Link request error: Connection closed!`

The link output comes fast. After this the program waits for about 60 seconds and terminates with a Lin request error.

What am I missing ?

log:
