Concordium Node Help Needed

Hey!

I tried following the Concordium instructions here: https://developers.concordium.com/en/testnet4/testnet/guides/run-node.html

Unfortunately, when I get to actually launching the node, I get the following error:

I haven’t been able to find out how to fix this. I am waiting on a response from the testnet team, but it’s been a few days now…

Anyone got any tips?

One quick addition, when I try to download the new client it does not allow me.
