Hey there swathinanon. 

Thanks for dropping by the Community, I'm happy to help. There could be a number of reasons why your connection isn't syncing with Chase bank. First off, lets try using a different browser. Follow these steps to download a different broswer from what you're currently using. Please check to see the list of browsers supported by QuickBooks Online below:

• Chrome
• Firefox
• Safari 6.1 or higher
• Internet Explorer 10 or higher

For mobile devices:

• Safari (iOS 7 or higher)
• Chrome (Android 4.2 or higher)

If that doesn't work, let me know here and we can go from there. Thank you for your time and have a nice evening.
