Based on the screenshot, it looks like you're hitting a snag on the Leo wallet connection in LeoDex—probably the "Connect" or approval step failing. This could be a temporary glitch with wallet permissions (like MetaMask or Keystore not signing properly) or a network issue on Arbitrum.

Try these quick fixes:

1. Clear your browser cache and refresh the page.
2. Ensure your wallet is on Arbitrum mainnet and has enough ETH for gas.
3. If using Keystore, test LeoAuth for a smoother login (biometrics/password) as updated in June—avoids re-uploading files each time.

If it's still blocking, drop more details on the error message or your setup, and I'll dig deeper. Recent updates fixed a bunch of connection bugs!
