504 error on login

Hello people, I am facing a strange 504 nginx error on logging in. The server is very light on transactions and not large, I have updated, RAM is at 3gb, processor is 3.5GHz speed. This is new to me, There were no changes in the network config of the ubuntu OS or anything. Strangely, 1 user can login, but all other accounts including Administrator, roll and end up with a 504 error.

Can you share you console log or check your server log files for error details? Also, you can post technical queries on discuss.frappe.io
