Cardano-Node Preview Testnet PeerSelection Error

Question

I am running cardano-node 1.35.3 on Ubuntu 22.04 Docker container. I am attempting to run the node on the preview testnet. Below is the following error I get when running cardano-node.

Here is the Error that I am seeing

Here is my cardano-node run command cardano-node run --topology topology.json --database-path db --socket-path db/node.socket --host-addr 127.0.0.1 --port 3001 --config config.json

Answer 1

apt install netbase in your container. it worked out for me.

Answer 2

These logs look like an issue with you config.jason file in your public root section you are calling a service name that it can not find. Would need to see your config.jason file to comment more

Answer 3

Apparently the testnet does not work for cardano-node 1.35.3. I have to run cardano-node 1.35.2 to use the testnet

Answer 4

I had a similar issue. Have a look at the following answer, changing the host-addr worked in my case:
