If it's asking you for mods, then you are not using the same version of Tekkit as your server. Your server probably got updated to 3.1.3, but you have to manually update your client.

Verify which version the server is using. Load up the launcher and click options. Click the button for manual build selection, then in the drop down menu, select the same version that your server is using.
