Connecting to KeyDB?

I did the KeyDB template found at KeyDB - Launch on Fly.io · Fly

How do I connect to it now? I installed keydb-cli but when I use
keydb-cli -h the.ip.add.ress -a mylongpassword it hangs and doesn’t return, error, or respond to commands.

KeyDB is listening on port 10000 instead of the standard 6379. Try adding -p 10000.
