No route found for path: \"auth/login\" and request method: \"GET\"

I’ve just moved a project on a new server and we encounter the following error when trying to login. Any idea on what might be the problem?

{
    "status": "error",
    "message": "No route found for path: \"auth/login\" and request method: \"GET\"",
    "code": 404,
    "exception": "Exception",
    "key": null,
    "file": "../vendor/getkirby/cms/src/Http/Router.php",
    "line": 185,
    "details": [],
    "route": null
}

Hm, yes, that should be a post request, not a get request. Could you try another PHP version?

I’m currently unable to try another version, current version is 8.2.9

Edit: Downgraded to 8.1.23 and try to reintall the panel but still get the same result when trying to install

{
    "status": "error",
    "message": "No route found for path: \"system/install\" and request method: \"GET\"",
    "code": 404,
    "exception": "Exception",
    "key": null,
    "file": "../vendor/getkirby/cms/src/Http/Router.php",
    "line": 185,
    "details": [],
    "route": null
}

Just to clarify: The project works locally and it worked on a different remote server?
