Panel fail to fetch

[Joeysay]

I haven’t edited my website for 3 years and just tried to do something. But the panel cannot be opened.
My Kirby version: 3.5 and php 8.0
Error message

And error in terminal:

[404]: OPTIONS /api/auth

Try to use http://127.0.0.1:4000 instead of http://localhost:4000.

Thank you! Now it works.
