unexplained 404 error

[devster31]

Hello I'm running the following:

• qBittorrent version: v4.2.1
• qBittorrent Web API version: 2.4

When trying to use any qbittorrent-cli commands this is what happens:

qbt server info --url https://<fqdn>/qbt/ --username <username> --password <password> --print-stacktrace
QBittorrent.Client.QBittorrentClientRequestException: Response status code does not indicate success: 404 (Not Found).
   at QBittorrent.Client.Extensions.HttpClientExtensions.EnsureSuccessStatusCodeEx(HttpResponseMessage message)
   at QBittorrent.Client.QBittorrentClient.PostAsync(Func`2 builder, CancellationToken token, ApiLevel minApiLevel, ApiVersion minApiVersion)
   at QBittorrent.CommandLineInterface.Commands.ClientCommandBase.AuthenticateAsync(QBittorrentClient client)

   at McMaster.Extensions.CommandLineUtils.CommandLineApplication.<>c__DisplayClass142_0.<OnExecute>b__0()
   at QBittorrent.CommandLineInterface.Program.Main(String[] args)

However using another HTTP client works as expected:

http --follow --session <mysession> http://<fqdn>/qbt/api/v2/app/buildInfo

    "openssl": "1.1.1",
    "qt": "5.9.5",
    "zlib": "1.2.11"
}

http stands for httpie and I had already logged in with:

http -v --follow --session <mysession> http://<fqdn>/qbt/api/v2/auth/login  username==<username> password==<password>
HTTP/1.1 200 OK

Ok.

The entire connection flow includes a redirect as I'm hosting qBittorrent at /qbt:

I'm having the same issue! Has any solution/workaround been found? Thanks

if anyone's still wondering, it seems like qbittorrent-cli ignores the path part of the provided URL (and thus makes requests to https://blah/api/v2/... instead of e.g. https://blah/qbt/api/v2/...)

Fixed in version 1.8 (currently nightly builds, will be release in a few days)
