Hello! I see you're having trouble entering a battle in Bloons TD Battles 2 because it keeps saying there's no connection to the server. Let's try to figure this out together.

First, could you tell me a bit more about your internet connection? For example, are you connected via Wi-Fi or an Ethernet cable? Also, have you noticed if this happens all the time or only during specific moments? Any additional details will help.

In the meantime, here are some steps to try that often fix connection issues:

1. Check your internet connection: Make sure your device is properly connected to the internet. Try opening a website in your browser to confirm.

2. Restart the game: Fully close Bloons TD Battles 2, then relaunch it to refresh the connection.

3. Restart your router/modem: Power cycling your internet equipment can resolve temporary network glitches.

4. Disable VPN or Proxy if you use any: Sometimes these interfere with connecting to game servers.

5. Check Firewall or Antivirus settings: On Windows 10, sometimes security software blocks the game’s access to the internet. Make sure Bloons TD Battles 2 and related services are allowed.

6. Run the game as Administrator: Right-click the game’s icon and select “Run as Administrator” to give it proper permissions.

If after these steps you still see the no connection message, there might be a server-side issue or more advanced settings to check. Also, confirmation of any recent game updates or attempts to login from different devices would be useful.

Feel free to try these and let me know the results! We can dig deeper from there.

Are you satisfied with these initial steps?
