Welcome to our forum, @tkm2460! Thank you for reporting. There can be a number of causes for this issue, like temporary outages, attempting to view an unusually large file with many equations, etc. For temporary glitches, reloading the Paperpile tab and/or restarting the browser are always a good first try (in Chrome, you can type chrome://restart in the address bar and the browser will restart and reopen all your tabs of the current profile). But if the problem persists, let us know here, over our in-app messenger, or by emailing support@paperpile.com.
