Try disconnecting and reconnecting your wallet, or restart your browser. Check if the RPC endpoint is responding.
You may not have tokens on this network yet. You need to bridge assets from another chain or receive tokens on this specific network.
The network may be congested or RPC may be slow. Try a different RPC endpoint or increase gas price.
