I too have never gotten iCloud to work . I posted here in the Forum a few months ago and there were zero replies. It got moved by somebody into the bug area but then nobody ever did anything with it. Simply closed after a month. ---

I am having the same issue on Mac using terminal. I tried to update the token, tried deleting the remote and re-adding the remote (including clearing iCloud info from the config file).

For what it's worth, I am getting this error too on my HP Chromebook running Debian bookworm. I have use 'rclone config' to set this up before and it worked, but now, after deleting the drive and readding it, I get the same error as above. Is there possibly a config database that is holding an old credential that needs to be deleted? ---

Update: hand removed ~/.config/rclone/rclone.conf to see if it would work from scratch. It regenerated the file with a password that, I assume, is a session ID. However, the error says that it is am invalid session ID. Did Apple change the process and, thus, break Rclone? ---

This is a good test. I did the same, but just with defining a new config. I got the same error. It turns out we are not alone. See [Invalid Session Token while connecting to iCloud · Issue #8587 · rclone/rclone · GitHub](https://github.com/rclone/rclone/issues/8587) which also has a suggested workaround. Sounds like mixed luck on the workaround. ---

I'm adding to the thread here mainly to stay up to date. I have the same basic issues and have tried similar fixes: Ubuntu 24.04.3 system; rclone v1.70.3; have been very happily been using iclouddrive for several months prior. I first got the same bad token error, then deleted and re-created the config, and lastly seem to be stuck with the same HTTP 400 errors. Claude says this is most likely an unexpected change on the Apple side which makes sense to me. Hoping it's resolvable. ---

The latest discovery on [Issue #8587](https://github.com/rclone/rclone/issues/8587#issuecomment-3169264324) was that building rclone 1.71.0-DEV **from source** works, whereas the prebuilt binaries did not. I tried that and it finally fixed the problem for me. > **Here is a recap of how to do that:** > > Build it on a development machine with ‘go’ installed. It doesn’t have to be the same architecture or OS as where you want to run it eventually since it can easily be cross-compiled. E.g., I’ve compiled it on a MacBook Pro, for a Synology NAS (Linux, amd64). > > ```bash > git clone https://github.com/rclone/rclone.git > cd rclone > GOOS=linux GOARCH=amd64 CGO_ENABLED=0 go build > > ``` > > That will result in a `./rclone` binary that you have to copy onto your target machine. Optionally, you might want to consider running `go clean -modcache` afterwards since the build downloads a lot of dependencies onto your dev machine. ---

Tried this today without success. I built rclone v1.72.0-DEV from source to run on ubuntu 24.04 (64 bit), and received this error: `` `Error: HTTP error 400 (400 Bad Request) returned body: "{"success":false,"error":"Invalid Session Token"}"` ``` Most annoying! ---

Yeah, the community reports on that github issue have in the meantime also shown mixed success, i.e., it worked for some people, but not others. There is no clear understanding of the difference between the success and failure cases thought. Some people have started to suspect that Apple’s servers are throttling this. ---

It looks like there is now an explanation of the observed behavior and a workaround on github [Issue #8587](https://github.com/rclone/rclone/issues/8587#issuecomment-3240025307) that works for most (all?) people: Apple is apparently throttling/denying traffic based on what the request’s `user-agent` string is. When you compile from source, part of the `user-agent` string is different (i.e., the exact version number), which is why that worked for some people. If you explicitly set a random `user-agent` string, it seems that the request always goes through. I.e., `rclone --user-agent="your-own-random-string" config reconnect iclouddrive:` ---

Tried this today I can confirm that it solved the issue for me. ---

This is an amazing find. I can also confirm the –user-agent flag works for me. Many thanks! [Next page](https://forum.rclone.org/t/icloud-connect-not-working-http-error-400/52019.md?page=2)
