Last week I bought a Synology (918+) and starting running a Bitcoin full node (https://hub.docker.com/r/kylemanna/bitcoind).
To check whether the Bitcoin node can be found by the network, I checked on bitnodes.io with my external ip. Unfortunately my Bitcoin node is not reachable. I have forwarded ports 8333 - 8334 on my router. Checking whether port is open on canyouseeme.org, it gives as reason 'Connection refused'.
Another thing which confuses me is the following: if I check the logs, it gives the following (snapshot):

What my understanding is that
height is the block height. How can this be
height=1744387 when we're currently around block height 630335? What am I missing here?
Please note that I am both new to running a NAS and a Bitcoin full node, so any help is appreciated!
