Yes, I tested on multiple devices and browsers, and it’s not related to browser extensions.

What I’m seeing is user-specific, not device-specific:

- On any device where the **admin account was already logged in** , opening the site immediately results in **502 Bad Gateway**.

- In **incognito/private mode** , the site loads normally and I can reach the login page.

- From there, I can log in successfully with **another (non-admin) account** and the site works fine.

- But when I try to log in with the **admin account** , right after submitting the email and password, I consistently get **502** , and the page never loads.
