No route found for path: \"auth/login\"

I uploaded a kirby 4 (4.0.1) site with ftp. The frontend is working normal… locally the site & panel is running great. But when I try to login in the panel the following error message appears:

{
"status": "error",
"message": "No route found for path: \"auth/login\" and request method: \"GET\"",
"code": 404,
"key": null,
"details": []
}

Unfortunately I have no clue about the hosting. just know that it runs on php8.1.
How can I get the panel running?

i have exactly the same problem. did you fix it ?

I think it was because of a but in the php version. Can‘t remember exactly which, but something with 4.1.x.

Hope this helps.
