Wrong Login Info Cause Server Down Error

[YapWC]

Summary: After I login with either a wrong email or password the page redirect me to a Server Down Error.

Steps to reproduce: Login with a wrong email or password in the login page of seafile and the following error will be shown.

Expected behavior: The expected behavior would be to have a pop up message saying wrong login info and prompt user to retry.

Observed behavior: When login with wrong info the page redirect you to Server Down Error but I have verified that the seafile server is still working as normal.

Please include relevant error messages and/or screenshots
