Installing nem node testnet

Tech Support
#1

Hi there.
I try to install my own NEM testnet node with docker from nem-docker
So I have successfully installed docker image and downloaded NanoWallet. I have created wallet (in NanoWallet) and asked for some coins here.
Now I have a wallet with 200 XEM.
But the problem is that when I select a node which is not my localhost in node list in NanoWallet, everything is ok. But when I try to select my node (localhost) I got an error "Error at fetching account data, reason: address must be valid.

Why this happens? I guess that’s because my node is outdate and blocks are not synchronized. Am I right?
And what should I do to solve this problem?

Also when I want to retrieve info about transaction via api, I get an error.
For example, this transaction
Response of fetching http://127.0.0.1:7890/transaction/get?hash=35e03cb915cfd6852502119f780921d263627303768f159a62434e45c1779f1b is

Hi, Please provide output from
/node/extended-info
/chain/height
API calls for your local node.

Now I see what’s wrong with my node. As I understand “networkId”:104 means my node is connected to mainnet but not testnet. I missed 1 configuration file inside container. Now I have edited this file too and restarted node.
Now I don’t get error “address must be valid” when selecting my localhost node.
But when I select my node from node list balance of my wallet is 0 (other nodes show balance 200 XEM). Also block height in my node is 23811 but it’s increasing. When it’s big enough I’ll be able to see my funds, right?

@hungl yes. It was wrong network to which you were connected.
Node must be fully synchronized. Right now we have on testnet around 1613189 blocks.
