Problem description

Unable to sign into the Backendless developer dashboard. An error message was displayed “The system has encountered an error.”, so I got here via the “Report a problem” link.

Steps to reproduce

Please describe steps to reproduce starting from the first action.

  1. Go to Backendless
  2. Enter email and password
  3. Click Sign In
    After waiting a while, the error message is displayed.

I’m able to sign in now, but will leave this ticket up in case the stack trace helps track down any underlying issues.

@Nathan_Loring

Thank you for your message. We had some errors with the database, now it is fixed. We apologize for the inconvenience.
