Hi gautam1,
There are times that your browser is full of frequently-accessed page resources, causing QuickBooks Online (QBO), to act strange. You can log in to your QBO account using a private browser. This is to rule out any problems related to your browser. Here are the keyboard shortcuts:
- Google Chrome: Ctrl + Shift + N
- Mozilla Firefox: Ctrl + Shift + P
- Safari: Command + Option + P
If it works, clear your browser's cache to speed up the loading process of the QBO website and for the system to start fresh. Otherwise, you can use a different browser.
You can also use a different browser. However, if you're still getting the same error message, I suggest contacting the app provider to help you fix this.
In case you have a question, I've added this article about QuickBooks Online: Help Articles.
